Random gates – analog version

by bdu on Dec.24, 2008, under audio, drum machines, media, modular, plug-ins, software

Like I said in the last post, couldn’t wait to get home and try it with the modular.

In this installment, I replaced the timbres, now we have a real (distorted) 808 playing the static drum beat, and the modular being played by the midi output of my custom modules in plogue bidule. This time the pitch input of the random clock module is being fed by a short repeating sequence I played and looped into the sequencer…

The modular patch is very similar to the one used from this post, but with the self-playing part of the patch yoinked out and replaced with the gate output of the Doepfer midi->cv/gate converter module. Also, I went ahead and made the whole thing pitched, played from that same module. So yes, you can play FMed sine oscs through lowpass gates in a melodic way, and no, it doesn’t sound half bad when you do so, if you’re careful to tune things properly. Lastly, it’s slathered in reverb-ish delay courtesy of Audio Damage’s Ricochet multi-tap delay.

pseudo-random clocking

by bdu on Dec.24, 2008, under audio, drum machines, media, modular, pictures, plug-ins, software

I spent some time in Plogue Bidule today wiring up a pseudo random clock midi note generator.

This object takes a midi clock as an input, then chooses (randomly) various divisions of that clock to output midi notes. The midi pitches are either hard-set internal to the object or with external midi input. You can weight the divisions heavier by adding that division’s number multiple times in the number text field.

In the example audio below, the notes were chosen by a pseudo-random note generator I patched up awhile back, similar in function to this random gate generator, but for notes instead of gate divisions. The resulting midi was played by the Magical 8bit Plug, with D16’s Nepheton providing the static beat underneath so you can hear the original clock speed unaltered.

I’m looking forward to letting this bad boy loose on my modular, where I was intending on using it primarily as a clock source via midi->cv/gate conversion.

It’s worth mentioning that doing something like this in a pseudo-random way is the most difficult form, once you have that, it’s mostly a matter of *removing* bits of the module to, for instance, make one that switches divisions based upon the value of a midi CC input.

Bleeping away

by bdu on Dec.20, 2008, under audio, media, modular

Thanks to the generosity of a friend, I now have 6u of Doepfer up and running to go with the 6u of Analogue Systems I put together last weekend. This houses around half of the modules I own, which is certainly enough to have a lot of fun.

I spent the evening bleeping away in classic fashion with FMed model 15s and spiked Doepfer LPGs. Here’s a minute and a half of the self-playing patch:

More click than bleep…

by bdu on Nov.14, 2008, under audio, media, sampling

This was going around the internets yesterday, but it seemed relevant, to me.

For the more experimental among us, you might find recordings of failed hard disks to be useful sample source material.

Go forth and click away.
