Re: [200e] Control Voltage Ranges

this is correct. most CV inputs on the 200e will saturate at +10v, unlike
old 200 series modules. negative voltages will usually do nothing.

Thanks for the reply. I've forwarded it to Lippold; I'll let you all 
know how it goes.

Another important point is that the 281 EG's need a +12 V gate to 
trigger. Does the Continuum CV box put out such gates? I think it only 
does +5 V, doesn't it? If so, you won't be able to trigger the EG's.
What I do to overcome this problem is to add voltages in my 210e (a 
little bit from my 255 to help the gate from my TKB, and voila!).

See if this helps....

Thanks for that addition. I believe the CVC is programmable in 
firmware for a wide range of values, so it should be doable, but I'll 
forward this info to Lippold to be sure.

Although, in fact, I may not actually use the trigger outputs, at 
least not with envelopes. I've been testing the CVC with a 
Synthesizers.com system, and have found that I get the most 
expressive control by bypassing envelopes entirely and mapping the Z 
axis (pressure) directly to volume in the VCAs. That way, I can 
manually alter the "envelopes" directly with finger pressure, varying 
the attack, sustain, and decay at will independently for each voice. 
It feels much more expressive that way, rather than being tied to a 
fixed envelope for any voice.

According to Lippold, the CVC outputs a maximum range of -9.8 to +10 
volts. Perhaps +10 will be enough to trigger the EGs; if not, my 
system will include a 256e that can bring the voltages up to the 
correct level (if I even use the trigger outs for EGs, as I 
mentioned.)

Re: [200e] Re: Control Voltage Ranges

hm, this is a little misleading... both the 281e and the 281 produce pulses
a little shy of +12v but actually respond at considerably lower thresholds:
about +8.4v to trigger and +4 (or a little less) to sustain.

i'm looking at one of each right now just to make sure... interestingly, the
281 triggers at the sustain voltage when in sustain mode. behold: a bug,
methinks!

anyway, you will be fine with the continuum. again, basically nowhere in the
200e series will > +10v have any additional effect.

Thanks for clearing that up. Lippold will be happy....
