From Arp2500, this is based on the 1006 Filtamp, minus the amp.....it is squirty
The Giant Bono - a delay chip & a PLL with 2 vactrols.........just crap!
based on the ARP 1050 Mix-Sequencer, minus the switches and VCO. It is a standard 8 stage sequencer, or two four stage sequencers, or an 8 stage
sequential switch, or two 4 stage sequential switches (good for routing
audio and/or CV), or an 8 input mixer, or two 4 input mixers (with an 8
input output anyway) and there is a difference rectifier in there giving
the positive and negative results of the difference between stages
(1-4) and stages (5-8).
Also the LEDs spin around in a circle giving a nice light show.
16HP, no wiring, all smd.
There's actually not that many parts, the logic chips do all the work
Phaser/Flanger based on the Aries 329. It has 11 matched NPN pairs and a set of matched FETs. It is actually quite simple to match FETs, a circuit will be given in the build guide. Pretty much all surface mount.
FK1t VCF - inspired by the Korg FK-1 pedal. It has a similar topology to the early Korg filters found in the 700 and 800dv synths but uses vactrols. What could go wrong?
