CV and Trigger and ...

[peonytele]

hi everyone,some questions..
CV signal, i think, is to control OSC, with different Voltage value, the OSC get different tune...and what is the Trigger signal?Any different between CV and Trigger? i see some equip, like analogue solutions` drum mod, they all have Trigger Input, but what could trig them?
if they could be trigged, could i ajust the Trigger Signal to program a drum pattern, just like what we did on the programmable drum machine, to make 3/4, 4/4, 6/8... pattern?
thanks a lot!

A trigger or gate signal is usually used to trigger the envelopes, it's basically an on/off signal to indicate when a note has been pressed or the next step of a sequencer is activated, as opposed to a CV signal which can be any voltage between 0 and 5V (or beyond).

Hey peonytele, CV is the voltage used to control the synth's pitch, and the gate is used to trigger the envelope generator's to make the sound.

AFAIK Trigger is similar to gate, only gate can vary in length (depending on how long the note is held) and a trigger is always just a short 'pulse' of +5 voltage used most commonly to trigger a drum machine's sequencer/sounds from external sources.

I recently had a go at hooking up the trigger/clock etc of a TR-606 & SH-101, I had the "Low Tom" trigger out of the 606 routed into the 101's clock input, then I'd sequence different patterns on the 606, and hold a basic "chord" on the 101 in "Arpegiate U&D" mode - so you get the notes playing along to the 606's beat, all in synch - also tried it on a system 100, with an awesome bass sound (sounded very Aphex Twin with the 606), a heap of fun to be had with the old Rolands

a,thank you Stab Frenzy and Hybrid88!
and what i think is, as you said, for example, if i want to make any patterns i want with some old synths` sound, i just need to get a "programmable drum machine with individual trigger output" (like TR606)?
and i have tried sq10 with ms20, it seems the CV signal can`t make it sound like a drum beat...and the only thing i could change on the Trigger output of the sq10 is just the speed...

a, one more question to Hyndrid88:
could i use a drum sound(maybe a short and high-level symbal sound) as a trigger signal? because i see the tr606 only have DIN out.

that's a matter of programming the MS, not the CVs problem... just for one drum sound, you dont really need CV anyway

[peonytele]

yes pflosi, you are right.
and my problem is, if i use CV to make a pattern, the sound is ok, but it is hard to get all the steps at the same pitch...hard to play live..

[pflosi]

just don't connect the cv to the MS cv input and adjust pitch by pressing keys / octave switch / fine tune... no problem at all. that way you can even play your drums with the keys

The TR606 has two trigger outs for the Toms.
As far as using audio as a drum trigger, it's possible, but takes alot of experimentation to get it right. The sound must be very, very short, like a TR909 rimshot, and you will likely have to spend time adjusting the volume.
If the sound is not short, it will usually causes repeated triggers for the duration of the sound.

[peonytele]

cool, i will try it!
thank you guys

use it with my sampler's (Esx1) ind. outs all the time to sync my jx3p's seq

used to use it for computer audio out->gear, until i got a mobius..

works like a charm just gotta fudge with your level a bit till you have it perfect (which doesnt take much).

the cool thing about using a sample to step advance a sequencer is that you can get alot of pattern variety out of notes you've entered by sequencing the trig in various patterns instead of just using it like a clock. then again, all those x0x's have trig outs and not clock so i guess it's the same thing. anyways, good times. it's also a good way to get the most bang for your buck outta limited note storage on an old synth

[pflosi]

yes, on the classic drum machines and x0x devices thats exactly how it works. it's never a clock, most of the time it's the rim shot triggering the gate, or just the notes on e.g. a 303
