[motm] RE: midi LFO module

2003-02-03 by media.nai@rcn.com

There are numerous gizmos that can extract a hardware clock from MIDI.

While the 320 does have a sync input which is very useful, it's not 
the same as being able to sync the rate to an incoming clock -- the 
sync input merely resets the waveform.

You can produce an LFO synced to a clock if you divide it down and 
then shape it with a lag processor.  This works if the divider 
produces a square wave or preserves the duty cycle of its input. 
However you have to re-adjust the lag processor if the speed of the 
clock changes.

Other than that, it's impossible to sync an LFO to a clock using 
analogue.  I saw a mock-up of the VC pulse divider that had a "ramp" 
output, and I suggested to Encore that they include a clock input for 
the digital oscillators in the frequency shifter.

The ability to produce LFO's synced to MIDI clock is a very nice 
feature for a MIDI-->CV converter, but I would like to see a module 
that can produce dedicated waveforms synchronized to a hardware clock.
