200e

These are 5 each patch comparisons of my Buchla 259 and 261e.  Each is a
320mbps mp3 file about 15 - 30 seconds each.  No routing through a
filter, just a Plan-B Model 13 Multi-timbral Gate, a vactrol based copy
of the 292e.

Assigning the Mod Osc to Amplitude and Pitch of Main Osc.  The 261e Mod
Osc has no Sawtooth so can't slam like the 259 because the 259 has
Vactrols in it's internal VCA, like the 292.  I used a tight rectangle
on the 261e to get close:

The Modulation Osc at Pitch Levels. For 259, using switch between Saw,
Pulse and Tri.  261e has waveshaper between Sine and Rectangle

My conclusion.  They are definitely the same breed and go into similar
sonic territory.  The 261e has a more functional modulation Osc but no
actual sawtooth.  The main osc on the 261e can go many more sonic places
but can't make a heavy analog sound like 259's meaty sawtooth.

Very nice.

I have one of each also (soon to be two 259's and one 261e), and have 
noticed that the 261e does exhibit some pitch jitter, kind of like the 
259e (but not as bad). I also find the main oscillator of the 261e 
rather thin in comparison. The mod osc in the 261e has an awesome PWM 
sound that makes up for the lack of sawtooth wave. 
It's great to have one of each, even though they are so similar...
