Roland System 100m

I've been using my Kenton Pro Solo II for a while now -- just got around to studying the 
manual (again, trying to get clock divide right) --

In any case -- it says

"- you can select the following types for the GATE output;

Gate V-Trig low (+5v)    [g, middle LED bar]
Gate V-Trig high (+15v)  [g, upper LED bar]

Gate is the most common signal used for telling a synth when to play its note. The high 
level  Gate is suitable for most synths, such as Roland, SCI, ARP, Oberheim. The low level 
gate may  be needed for synths that require a lower gate voltage such as the SH-101."

What's the proper gate V for the 100M?  If I've been using 15V at times, is that OK (no 
harm done)?

No harm done. Roland's own 181 keyboard puts out >12V on the GATE output.

Hi Robert

A bit more info on the gate signal.  The 100M gate generator circuit 
diagram shows the Gate ouput to be from -0.96V to +13.6V and the 
Trig output to be from 0V to +15V.  The Env Generator gate input 
threshold is shown to be about +3V.  So you should be able to use 
any gate/trig that swings from about 0V to at least +3V and all the 
way up to +15V.  In fact the Env input has protection allowing even 
bidirectional signals to be used as a gate.  Try using the LFO and 
S/H Clock outputs to trigger the Env Generators.

Cheers
Tony
