Tiptop Audio DSP Feedback Loops

"Sitting at the core (or left of center, depending on how you look at it) of the Z5000 VCDSP is the Tiptop Audio 24-Bit DSP. What makes it even more unique is that because the modular format allows patching to and from anywhere in a system it is fairly easy to make very interesting use of the 16 different algorithms that the DSP contains.

All of the algorithms in the DSP work differently. Some handle the signal on two separate channels (like the delay effects), but the reverb algorithms, work entirely differently, mixing and processing the signal together using both processors.

Using that delightful feature, it is possible to send a signal into the left input and then feed the left output back to the module's right input that to create a wild feedback loop that makes the module to oscillate and create its own sounds and timbres, similar to the way filter resonance works. This oscillation will continue as long as the CTRL knob is set to MAX, and will decay as the knob is turned to MIN.

Technically, the module should start oscillating even with out any external signal. Using a sound source, however, gives you the ability to "trigger" and control the oscillation and also blends the oscillation timbre with that of the incoming sound source.

Check out the sample below for those long oscillations fading in and out as the sound source triggers them. It's nice to hear how the sound source is changes the tone of this oscillation each time it cycles."

You can find the sample here.

"This is the Korg Kaoss Pad (KP3) playing Korg MS-20 samples. All sounds (including rythm section) are created using only the Korg MS-20! The KP3 is used for sampling the sounds, and for adding effects.

I posted another vid explaining how the samples are made from scratch. So if you have an MS-20 and/or KP3 you should definitely check this out!"

ARP Avatar Guitar Synthesizer Owners Manual

via this auction

via Loscha.

"Original manual for the Arp Avatar Guitar Synthesizer. 52 pages (including covers) The manual is writing primarily as a guide for Guitarists and other people who are new to synthesis, however, the structured exercises in the book are a valuable learning tool for anyone who is using analog synthesizer, but especially good if you have a related ARP product (such as the Odyssey)... Cover still very slick; It is a matt slightly gloss finish."
