Here is a data assignment for the lower drawbar. All lower drawbars use CC#81 (51h) (midi channel 2) dividing the drawbar settings (0-8) within the 0 – 80 out of 127 available values:
16’........0 - 8 (00h – 08h)
5 1/3’....9 – 17 (09h – 11h)
8’........18 – 26 (12h – 1Ah)
4'........27 – 35 (1Bh – 23h)
2 2/3’ .36 – 44 (24h – 2Ch)
2’........45 – 53 (2Dh – 35h)
1 3/5'..54 – 62 (36h – 3Eh)
1 1/3'..63 – 71 (3Fh – 47h)
1’........72 – 80 (48h – 50h)
Would it be possible to program this data set into the midi cpu?

I own a Hammond XMc-2 drawbar controller, which uses a proprietary communication protocol. I purchased this drawbar controller by mistake. I thought that the XMc-2 was transmitting midi messages.
I would like to remove the control board from the Xmc-2 and install the midi cpu board with the proper midi mapping for the lower drawbar.

So my MIDI CPU is on its way, and I'm looking to build a MIDI footcontroller for my Eleven Rack guitar processor. I had a few questions before I create my layout.

1. As far as I understand, a rotary encoder can/will act like a potentiometer that can turn continuously and freely. Is this accurate?

2. If I wanted LED indicators to light up when using latching SPST switches, I know I could write some code and utilize some of the other terminal points, however, could I instead just wire the LEDs directly into the SPST switches themselves, that way they would turn on when the switches are engaged? Or would there be voltage/current issues with this approach?

3. Say I have a few SPSTs, a rotary encoder or two, and some potentiometers, they all have a certain function/issue a certain command. Is it possible to then wire things up so that they could also perform completely different functions upon depressing a push-button switch (or something similar)? In other words, can I toggle the functions of all the buttons/encoders/pots by toggling just one switch?

Thanks so much!

I ran across this nice looking setup:

It's called the Saitek X45 Digital Joystick & Throttle. And boy does it have a bunch of switches and rotary controls..
Here's the full manual- http://www.saitek.com/manuals/X45_Manual_update.pdf

I ran across two schematics for it. The first one shows both the Joystick (SH 1&2) and the Throttle (TH 3&4).
Below that it shows the pots for the joystick, throttle, two rotary controls and the rudder control (on back/bottom of throttle).

Now I'm mainly interested in that throttle control. So lets just forget about the joystick entirely for right now.
I might get back to the joystick another time though.. :D
Right above here you should see pots TH, RD, R1, R2.
Four pots that are most likely 100K Ohm each. I might be able to change them out to 10K Ohm, but doubt it'd be easy..
so I'd have to do something to them so the Midi CPU could use the signal.

Below is another schematic of the throttle only. It appears to be the stock DB 15 connector wire colors.. the 15 pin #'s can be seen in the prev. schematic.
I'd think that DB15 connector would be simple to create a socket interface to the MIDI CPU..

I got that from this site-
http://www.brewsterbuffalos.com/x45/

now that site is showing how to make the DB15 connector to a USB connection with the throttle controller.. something I'm not interested in doing.
(The throttle controller plugs into the Joystick with the 15pin connector, then the joystick ouputs a USB to the computer.)
I just thought it was very helpful to get an inside look at the unit and that handy schematic to do some investigating on using it for a midi controller.

Can you tell if the switch matrix and pots would all "fit" onto the Midi CPU?
I see a ton of potential with this thing if done right. Pitch Bend, Mod, Filter Cutoff, LFO, Up/Down switches for several CC's.

Secondly.. would both controllers fit?

Here's what I'm trying to achieve.

One Octave of 12 push buttons playing notes C1 to B#1 - MIDI note 36 to 48
I have a 4x4 Switch Matrix with 9 terminals labled G1234ABCD, I sort of got it to do something, but I think I've either wired it wrong or it needs some sysex magic doing to it.

I would like to put a light sensor in the circuit that effects the velocity of these notes.

Four Pots, CC#71, CC#72, CC#73, CC#74
These Control virtual rotaries on a device called the combinator in Reason. Once I control these I can program their funtion within reason

Four Switches CC#75, CC#76, CC#77, CC#78 (May be swapped for Pots so could be treated as such)
These are, as above, buttons for the Combinator. The can respond to pots controlling them and a value of 63 or more turns them on. However, as there is a limitation on the number of pots that can be use, these can be switches.

Slide Pot Mod Wheel Midi CC#1
The Mod wheel is always something handy to have control of. This would be great with a light sensor

Slide Pot Master Volume Midi CC#7
Any devices in reason with it's own level is controlled by this cc.

6pots, 4switches

CC#61Pot, CC#62Pot, CC#63switch, CC#67switch (//thor's rotaries and buttons)
Thor is a programmable synth so, like the combinator, these are good for live user input to manipulate.

8pots, 6switches and a 4x4 matrix with a global velocity doodah.

Stumbling Blocks

I don't have the space to lay it all out in front of me and have a good think.
I'm struggling to get my head round coding and I still dont have anything practical to house the project in.

I'm having some trouble getting my configuration into the CPU. I did the preliminary tests and get MIDI data thru the CPU, sent routed using MIDI-OX and a Roland UM-2 Super MPU32 MIDI USB interface, but cannot seem to affect the program in the CPU when I send chunks. I also tried a half dozen other MIDI interfaces I own, from cheapy Amazon from China up to an M-Audio LightBridge firewire. Sqwerl rejects them all - so it oculd be the interfaces, but they all receive fromt he CPU fine. I've also swapped cables.

I'm using MIDI-OX on Vista-32 with SP2 to talk to the CPU.

I'm trying to program 4 N.O. momentary footswitches and one 10K ohm potentiometer control. The wiring checks good with an ohm meter. I can post photos, but the switches send the default notes, so I think that is a good basic test of connectivity.

I may just not get how to send the chunks, but I am able to get a sysex dump, so I think I get that part.

My footer includes the XBEEs description, but I'm doing that after I get the CPUs working via wired MIDI. So the XBEEs are not yet in the circuit. It's straight MIDI for now.

I'm new to the board after finding the MIDI CPU product recently in my attempts to customize a synthesizer of mine.
I've gone over what I can digest in two short evenings on what it is and how it works.

I am curious if perhaps you can tell me if this scenario is possible to do with the MIDI CPU unit... I want to use encoders for CC's just like this:

http://www.sparkfun.com/products/10982

It is a RGB LED lit shaft 24 position encoder with a push down momentary switch. There are 3 LED's built into the encoder, making a total of 7 different colors possible in multiple combinations of on/off.
I would most likely only use 5 colors total.. if that.

From what I've read so far on the MIDI CPU, it looks like I could possibly get on just one board:

4 encoders
a matrix of 15 LED's to drive (3 com/ 5 data)
4 switches to serve the momentary switches built into the encoders and that leaves...
4 control lines to spare (4 switches, or two more encoders.. or one encoder/ 2 switches.. ) to do whatever there is left to tweak in.

What I want to do with the built in momentary switch on the encoder is to make it so one knob can become several different knobs (one at a time). At a glance, you can visually see what CC each encoder is going to operate simply by the color indicated on the knob itself (using transparent knobs).

Example:

3 encoders (for simplicity) with RGB led shafts.. all in a row. At default/powerup, all knobs are lit GREEN. Now press down on the middle encoder. The status will now change to RED on that encoder and it will change what CC it alters.. meanwhile the other two encoders remain green. So you see Green, Red, Green to show that the middle encoder has changed what it's going to control.
Press the middle one again and it changes to BLUE.. so now you have Green, Blue, Green encoders.. and once again, the middle encoder has changed to a different controller.
Press the right most encoder in and it will go from Green to Red.. so now you have Green, Blue, Red.

So in essence, just using the colors Red, Green, and Blue, you could make three knobs control nine different parameters. If you have four encoders, then you'd have 12 different CC's that they could do.

I chose a LED matrix of 15... so 12 LED's could be controlled individually, and if desired, a way to MIX colors to provide additional CC's. I believe you can get up to 7 different colors on one knob. On top of Red, Green, Blue, you can also get Turquoise, Yellow, Purple and White (well.. a bluish white).
The extra 3 LED drivers in the matrix would be for other uses.. like a couple extra momentary switches seperate from the encoders.

Although 7 simple color combos sound nice, I most likely will stick with-
Green, Yellow, Red, Blue, Purple. 5 different colors that are easily discernible from each other.
If that were so, then 4 encoders could be made to do 4x5 CC's.. or 20 different CC's with just 4 knobs.
And of course the colors will cycle thru. Press an encoder down 5x to get from Green, back to Green again, for example.

Is it possible to configure the MIDI CPU to do something like this? I realize it can be configured to decode encoders, it can detect a trigger from a momentary switch, it can drive LEDs.. but can these all interact with each other as described above?

Thanks in advance,

I'm building a MIDI controller based on two MIDI CPUs chained together. However, there's a few things I'm not clear about regarding pots and encoders.

1. How can I figure out what data register address I should assign to each pot (for the d1 slot of the code)? I can't find this in the documentation. In the setup examples, the first pot starts at d1=03 with further ones ascending, but what does this mean?

2. I have a rotary encoder set up with the following code:

Code:

00 00 14 00 01 11

01 00 14 00 01 11

However, it behaves like a switch that is constantly opening and closing when I turn it, giving me fully high or low values rather than incremental values.

Thanks in advance!

I'm KissKong from France, so I'm sorry if my sentences are not clear but I try to explain properly my project ! ;)

I'm 23, and I'm a DJ. I want to make my custom Midi Controller for my sets. I use a Kontrol S4, a Kontrol X1 and a Korg NanoPad.

I want to make a Midi controller to replace the Kontrol X1 and the Nanopad :

So to replace the pads of the Korg Nanopad I want to use Arcade Button like a MidiFighter from DJtechtool.

I want to use also another parts like touch strip.

My project has 64 leds, 8 potentiometers, and 35 switches.

For this reason, I should use 2 midi boards. I planned to use a M-audio Midisport adapter to have an USB port, and I planned to use the 5V of this USB to powered the both boards, it's will be ok ?

The first midi board will be for the 8 potentiometers (inputs 16 to 23) and the first Matrix of 35 switches (7 date lines x 5 select lines - inputs 0 to 11).

The second midi board will be for the second Matrix of 64 Leds (8x8 - inputs 0 to 15).

I precise that the 8 potentiometers includes 5 classical potentiometers, and 3 touch strips like this :

http://www.trossenrobotics.com/store...eter-50mm.aspx

I know yet that I should program each midi board separately, but I don't know how program them (code and with the computer, there is a software ?)

For the Switches Matrix I should use diodes for each switch ? If more than one button is pressed at once they don't interfere with each other ? What type of diodes I should use ?

First of all, could you help me for programming the boards please ?

thanks for reading, sorry again if my sentences are not clear.

I wanted to start a discussion on hardware devices for recording, storing, transferring, an playing back MIDI files. Both for posterity and because I have a project that would benefit from this knowledge.

Devices that have come up so far are the Yamaha QY series, and some older devices including the Alesis MMT8 and the Korg SQ8.

Theres also this beast, which would frankly be perfect for what I'm doing if it didnt cost as much as old laptop would. (An old laptop made out of solid gold.)

http://www.sdmidicontroller.com/

Does anyone have any experience with any of these, or have other ideas that future inventors might like to know about? I took a look through the blog, but if there's anything I missed please feel free to include it. I was frankly surprised that even the Great American Horn Machine runs from a laptop.

For my own purposes, it would be amazing to have something that could shuffle and playback midi files and output them to other devices.

The MG-1 includes features such as:

Two oscillators with sync & detune, one producing either a Square or Sawtooth waveform, with the other producing either a Pulse or Sawtooth waveform.
One 24db/oct low pass filter/VCF, that can use the envelope generator, has three-position keyboard tracking, and is capable of self oscillation.
Three-part envelope generator, with separately adjustable Attack and Decay or Release, and selectable Sustain on or off. The Envelope Generator can be triggered by either the keyboard, or the LFO.
Oscillator 2 can be tuned independently or hard-synced to Oscillator 1.
Noise generator. (Digital Pseudo-Random Noise)
Ring modulation (called "Bell Tone" this is Amplitude Modulation of VCO 1 and 2).
Polyphonic oscillator. This is a divide-down square wave generator. It is routed to the VCF and the VCA.
LFO that can modulate the oscillators and the filter using a Triangle, square or random Sample and Hold waveform
Voltage controlled amplifier with Keyed, Hold, and Envelope modes (accessed via 3-way switch, misleadingly only labeled "Tone Sources" but also affects Poly signal)
Portamento (called "Glide")
External Control inputs for pre-MIDI CV/Gate.

According to the current MPA firmware manual, you can toggle a logic output using Note On status messages (logic modes 02 and 13).

The gear I'm working with doesn't generate Note Off messages, but rather Note On/velocity 0 messages (as is common in a lot of MIDI gear), so I'm assuming the MPA's note toggle features won't work with my gear (effectively working the same as logic modes 00 and 11).

Given the following MPA sysex config for logic output #1:

F0 00 01 5D 01 00 02 00 00 02 01 00 02 02 00 02 03 00 13 00 00 3D 00 3E 00 3F 00 40 00 41 00 42 00 43 3F 3F 3F 3F 00 00 00 00 00 00 00 00 F7

What will happen in the current firmware when it receives a MIDI status 9n 00 message (Note On/Velocity=0)?

Will it be:

1. processed as a Note Off message (MIDI Status 8n vv) and ignored (the logic output will not be toggled/latched).

or

2. processed as a Note On message (MIDI Status 9n 00) and the logic output will be toggled/latched.

If #1, then where do I place my order and how fast does it ship? :)

If #2, then can I submit an urgent feature request for the next MPA firmware release to have it optionally process MIDI Status 9n 00 messages (Note On/velocity 0) as MIDI Status 8n vv (Note Off) messages (ie not toggle/latch when it receives 9n 00 midi status messages)?

Also, it would be great to be able to set separate MIDI channels for each logic output.
