Dave Smith Instruments SYNTHESIZERS

Dale, according to DSI's response you shouldn't have to worry about watching the levels on those CV inputs - the circuits are "protected from higher and negative voltages, so you shouldn't have to worry about damaging it." It sounds like the worst that could happen is "clipping" the CV source causing you to get results you don't necessarily expect. ie Expecting full CV when variable pedal is fully engaged however only getting partial response.....

Have fun experimenting! Let us know how the GR-20 & the PEK play together!

Subject: Re: [Evolver] UPDATE Regarding CV1 & CV2 (pedal) inputs!!!

in my case I also want to try other modulation paths from audio effects in etc...
 
btw .. I picked up a GR-20 Roland for my Les Paul .. so far I managed to install the pick up
and go thru the presets on it .. next is input to the synths .. i.e. the PEK ... ;-)
 
thanks for posting this .. I'll have to watch the output levels of some of the pedals and effects I have ..
wondering about the response time

Hey guys, I wrote to DSI a couple days ago asking what voltages are safe to run through the CV1 & CV2 pedal inputs.
 
Here is my question:
 
I have a question regarding the pedal/CV inputs on the PEK.

What voltage is safe to run through them?

ie I have a modular synth, would it be safe to run its LFO, EG, etc through the pedal/CV inputs on the PEK??? Will audio rate voltages (volt/octave) hurt the synth if I run a VCO through it?

I'm not going to try this until I hear back from you guys as I don't want to ruin my board, however it is a feature I would like to exploit if I can (if it is safe and won't void my warranty).

Thanks,
Jim
 
 
Here is my answer:
 
Hi James:
 
The CV input responds to a range of 0 to 5 volts. It is protected from higher and negative voltages, so you shouldn't have to worry about damaging it. Audio rate voltages won't hurt anything, but the inputs are heavily filtered, so it will not respond to fast CVs. Slower LFOs, envelopes, etc., will work fine.
 
Cheers,
 
Andrew McGowan

So.... modulate away fellow Evolverers!!
