Default umr in siel mono?

would it be possible to midify a siel mono with a umr kit? has anybody tried this? can anybody tell from the siel schematics - which can be found here:

Hi Mic,

Haven't had a chance to study the schematic yet, but if you haven't already found it, there's some detailed information about installing the UMR here:

thanks, i've seen that page, of course. thing is, i don't currently own a siel mono, but i'm being offered one. i would buy it if i can find a way of either midifying it or adding cv/gate inputs.

so if you could have a look at the schematics and give your opinion on how likely a successful umr installation would be, that would be extremely helpful. unfortunately, i'm not electronics literate enough to determine this myself just by looking at the schematics.

Hi Mic,

The schematic shows a 4-select line x 12-data line matrix. Unfortunately, the current incarnation of the UMR only supports up to 8 data lines.

A future revision of the UMR may have this capability, but I'm not sure if/when that would happen.

In the meantime, there are other, less elegant / more costly ways to retrofit the keys.

You could place a relay in parallel with each keyswitch, and then control the relays with a regular MIDI decoder. Since there are 37 keys, you could either use two MD24 units and supply 37 of your own relays, or you could chain together 5 MSA-R units (8 relays each).

Let me know if you'd like to discuss further.
