Dual MOTM-485s + Env Follow

Dual MOTM-485s + Env Follow

2009-06-12 by Argitoth

http://www.elanhickler.com/misc/MOTM_Elan_init_patch.mp3

Used in this patch:

MOTM-310 uVCO
MOTM-190 uVCA
MOTM-190 uVCA
MOTM-820 Lag
MOTM-800 ADSR
MOTM-485 Filter (Modified: Doubled frequency cutoff range, simple
resistor change) Lowpass Mode
MOTM-485 Filter (Modified: Doubled frequency cutoff range, simple
resistor change) Lowpass Mode

Oakley Envelope Follower
Oakley ADSR/VCA

This is the standard patch I'd create with my current set of modules.
I don't yet have any LFOs, only one VCO, so it's barely a complete
system, but I love it to death, it's exactly what I hoped it would be.
The reason I am posting this is to show you how dual MOTM-485s can
sound. Actually, I aptly named this patching technique "Envelope
Follower Feedback." I am routing the oscillator into the filter into
the envelope follower and then back into itself and sending the
modulation to frequency cutoff.

In effect, the filter is modulating itself.

This gives the overall tone a constantly-changing and unpredictable
behavior which gives the patch lots of character. Add in the huge
range of tones you can get with MOTM-485s and you can create ripping
synth leads. Some of the higher notes' harmonics start to fold back, a
very nice affect that can be dialed in with the MOTM-485. Last note: I
modulated the CV Mod a bit.

Nice patch! I really like the way it sounds near the end when the filters
start singing in "falsetto"! ;-)  The MOTM-485 definitely rawkz!  Ad slogan
-> "The MOTM-485 VCF: People in the "know" have two, shouldn't you?" <laff>

Correction on the patch explanation, sorry:

Oscillator --> Filter (Audio In) --> Envelope Follower (Audio In)
Envelope Follower (Mod Out) --> Filter (Mod In)

Envelope Follower Audio Out --> Computer / Audio Mixer

The feedback is caused by the filter going into the envelope follower
while at the same time the envelope follower controls the filter
cutoff.

Less freq cutoff = more volume = more voltage from env follow to freq
mod = less freq cutoff

MOTM-830 IC question

2009-06-18 by Tom Adam

I'm building a MOTM-830 and I'm missing the OP285 IC's.
I've got OP275's, can I use these instead?
I will get the 285 eventually....
 
Cheers,

Yes, I need to update the manual. OP285GPs are no longer made (only SOIC). The '285 has lower DC offset, that is the only difference (same die, I'll bet).
