Drum sym and cynare trigger question

Drum sym and cynare trigger question

2007-07-18 by Tom Adam

I've tested my drum sym and cynare with a MOTM-800 ADSR and they are
working fine. But when I connect a MOTM-380 Quad LFO, these modules are
not triggerd. Did I do something wrong? I think the LFO gives a -5V to
5V sin or tri signal out. Or was it -2.5V to +2.5V, can't remember now.
Cheers,
Tom

The trigger input on the Cynare is AC coupled. It will only work with a
square or pulse type waveform. The MOTM-380 has -5V to +5V sine and
triangle waveforms only. You need to use a MOTM-390 or other LFO that
has square waves. Why did it work with the MOTM-800? Because you
dialed in a fast Attack time.

Richard,
Thanks, I was thinking it would be something like this. I've got a
MOTM-320 ready for power up. No need anymore for an ADSR to be
sacrificed for running the drumsym/cynare.
Cheers,
ToAd

howdy,

Why not try a battery powered schmitt trigger in betweenthe LFO and
the module. Dpending on the frequency, the battery might last quite a
while using 3 0r 4 "D" cells.

Howdy,

A +5 volt line from the synth would run the scmitt trigger just fine
also. If it's an inverting trigger, of course you'd have to follow it
with an inverter/buffer. A very small proto board and your good to go.

Howdy,

Or, find a 15 volt source and ground on the synth and power a
schmitt trigger from that.
