LFO question

LFO question

2001-05-12 by John

What shape is the Saw output on the 320?  Is it a rising slope with a 
falling vertical edge or a vertical slope?

Both. You can choose it with the "Shape" control.
Actually, you can continuously "fold" the waveform from positive
saw to triangle to negative saw, as on a EMS VCS3 oscillator.

Right and to further clarify, SHAPE at 1 gives saw up, 5 is triangle 
and 10 is saw down.  Hook it directly to a VCO and have a listen...

Very cool.  I am assuming this can be done with voltage control as 
well seeing as there is a Shape In jack.  What does the Shape do to 
the other outs (sine tri and pulse)?

Tri: no effect

Pulse: narrow to 50% (square) to wide

Sine: Hard to describe without picture (it's in the manual). Sort of 'peaky'
to 'hilly'

Yes, SHAPE is controllable via CV.  Paul already described what 
happens with each waveform in another reply.  My favorite trick is to 
send one of the wave outs to the S&H IN of the 101 (Noise/S&H module) 
then play with the SHAPE control of the 320 to change 
the 'sequence'.  You can get an amazing number of patterns this way.
