Thanks for taking the time to do this Ed.
Program change seems to be 'instant' which with some trickery might let us simulate how the run generator in SDS 1 operate
https://www.youtube.com/watch?v=EokXz8mAVyUMy initial quest where to alter sound parameters on the note decay in a sequencer setup. The track is a little too busy for me to actually hear if the envelope close at program change? Where you able to hear this? I don't expect it to close tho.
Anyway, I had my thinking cap on since I posted my question. I had this number 7.3ms in my head, which seems reasonable fast to output sound parameters. But when calculating this the way SDS7 actually update sound parameters we have to multiply by 12 independed of actual numbers of drum modules. Meaning a single parameter like Voice Pitch on a dedicated module are updated every 88ms.
Still this should be fast enough to play 'musically' notes chromatically with a single drum module with this program change trick. Where a series of identical drum kit are stored and only Pitch (or whatever other parameter one might like to use as effect) are changed.
Regarding connectors, we might get the numbers of up if this actually can be used musically interesting. If so I plan to make a 5$ worth in parts MIDI to program change converter which relatively easily can be made to do simple 5V triggers. Then this idea might be interesting for non MTM owners who also use their SDS7 in a sequencer setup.
$15 seems exaggerated for the connector thought. Is this a NOS Simmons part or from an electronic supplier? I remember I once looked for what I thought was a rare multi-pin connector and found them dirt cheap at some eastern sellers.

Just using the Selector Pad. I still have to make MTM>SDS7 cables which are gonna expensive - connectors alone are over $15 each. Hit me up if you're interested. It'd be nice to make enough of them to get price breaks to keep the cost down.
