Semi-random patch

Semi-random patch

2002-10-19 by John Loffink

Ingredients:
Any 2 LFOs
MOTM-700 Dual VC Router
MOTM-820 VC Lag

Any LFO 1 waveform to 700 IO A
Any LFO 2 waveform to 700 IO B
700 IO X to 820 IN
820 OUT1 to 700 CV IN
820 OUT2 to any control voltage input, VCO pitch, VCF cutoff, etc.

LFO rate, Router switch, and Lag Up, Down and Up/Down will cause
significant change to the semi-random pattern.  Adjusting the Lag
control too far to the right may cause the Router to stay pegged to one
side. The patch creates a feedback path so that lagged versions of LFO 1
and LFO 2 alternate control of the router switching.

Very nice!  I added LFOs from the 380 to control UP, DOWN, and 
UP/DOWN on the 820, too...

Re: [motm] Semi-random patch

hello all,
brilliant, not had a patch post for a while
mine quickly evolved into quite a complex snare patch once i'd decided to
hook a diy drum pad up to it

meanwhile on the MOTM650 front, can i shake things up by asking the
following:

"anyone out there have a need for a kind of masterclock, that is an LFO with
pulse outputs, maybe some simple pulse division, but more importantly a
midiclock output..?"

i'd find this a very powerful addition to any modular system
cheers

Commonly referred to as a TPG (Timing Pulse Generator) and sometimes a clock source.  I have a wish list drawn up on paper.
And yes, I would love to have one for my system in MOTM format!!!\

midiclock output (was: Semi-random patch)

Yes, I think there is a need for MIDI clock output, which is why I
suggested that the MOTM-650 have a MIDI clock out (since it has an hardware
clock in).

Any module with a pulse output can be used as a master clock.

I use a Garfield Dr. Click, which I will sell when then VC Pulse Divider is
available.  The Dr. Click has can divide clocks and has a vast multitude of
inputs and outputs.  However, it takes up quite a bit of horizontal space,
and I am trying to shrink my studio to a fraction of its size while
retaining its full-sized power.  You know, like Antman :)

If I use MIDI as the master clock, I can run the Dr. Click off of the DIN
or arppeggiator out of the Pro-4.  This way I can run x0xboxes synced at
different tempos without having to rewrite the patterns.

The Dr. Click can also be used as a master clock or slaved to any sort of
pulse clock -- DIN, drum triggers, 303 gates, MOTM-320, etc.  Then I can
use the DIN input of the 909 or the "tap" inputs of he PCM-80 to convert
that to MIDI clock.

Since I am keeping the 909, Pro-4 and PCM-80, I won't need the Dr. Click.
Although I am thinking of getting two pulse dividers.

Anyway, while the VC Pulse Divider can divide by 24, it cannot multiply by
24, so it cannot generate DIN clock from a 1ppq hardware clock.  This is
one reason why the MOTM-650 should have an output for MIDI clock.  A DIN
Sync24 output would be useful as well, but it's not as necessary since most
people with such gear have some way converting MIDI clock to Sync24.  Maybe
someone could get a Stooge panel for that Blacet chip.  I most frequently
use my Pro-4, but admittedly, having a DIN Sync output is an extra feature
that goes beyond MIDI-->CV conversion.

Btw, how far up does VC Pulse Divider go??  Is it possible to design a VC
pulse multiplier as well??

i think, what i meant was a unit that could specifically link a modular TO a
digital audio workstation
i like to jam on my MOTM but be able to record loops in tempo
currently i run a pre-determined tempo on my DAW and loop it back to my
modular
i'd much prefer that my MOTM could run things direct - in fact i'm certain
it's the sort of thing that a lot of modular users would appreciate in
general

Didn't Paul say that the proposed MOTM-650 could sync to MIDI as well?

Right now, it does "MIDI Clock Extraction", as opposed to "MIDI Clock Generation". Hmmm...I
suppose the reply is the infamous "It's only software!"

You mentioned MIDI clock out on a 1/4" jack, which I presume is a pulse
train driven by the MIDI Timing Clock at the MIDI IN jack.

What I meant is MIDI Timing Clock coming out of the MIDI OUT jack driven by
a pulse at the Ext Clock 1/4" jack.

Or are you saying it does both??

Imho, MIDI Timing Clock, which only communicates tempo, does not have
sufficient resolution to sync audio.

MIDI Time Code communicates both "tape speed" and location, and can be used
to sync audio, but does not communicate tempo.  So MTC cannot be generated
from MIDI clock, and MIDI clock cannot be generated from MTC, without
having more information about the "song".

While the simple pulses used by most hardware sequencers can be converted
to MIDI clock, they cannot be converted to MTC.  Even if they could be
converted to MTC, it's generally not a good idea to sync a DAW to an
external clock anyway.

Both MIDI Clock and Roland DIN Sync24 use start and stop commands, and 24
pulses per quarter note, so they are easily converted into each other.
Btw, both MIDI Timing Clock and MTC may be used along with MIDI Song
Position Pointer.

If that's not confusing enough, MIDI Timing Clock and MIDI Time Code have
the same initials.  Lucky for us, MTC only refers only to MIDI Time Code.
MIDI Timing Clock is also called "beat clock" or "MIDI Sync" although
neither term is in the specification.  Regardless, that's what people mean
when they say "MIDI clock", although I think Paul S. might be referring to
a pulse output driven by MIDI clock.

Having a MIDI Clock output would be useful in syncing other MIDI devices
(sequencers, delays, keyboard arpeggiators, drum machines, etc.) to the Ext
Clock input.  That way you could use your MOTM to "run things direct".
