MATTSON MINI MODULAR VCO TEST MMM

YouTube via redmartian
"Testing two the new VCOs. One sample and hold is routed to the modulation input of VCO 2 and the second sample and hold is routed to the CV input of VCO 2. VCO 2's triangle is then fed as modulation input of VCO 1 which then has two square waves and a saw tooth mixed in output."

October 15, 2008 Jupiter 8 Update

"My tech said the Jupe 8 was ready - all calibrate and Encore MIDI kit installed. This thing sounds amazing, but the VCA for 4 voices is not right. You can tell that 4 trigger with instant attack, but the other 4 have slower attacks."

Why does the Juno-60 sound different from the Juno-106?

"So let's start by getting a couple of things on the board out front. The VCO, VCF, and VCA circuits are nearly identical. "How can you say that", you might ask, "when the 106 uses those 80017A's that keep failing, and the 60 doesn't?" Consider: The 60 uses a VCF filter circuit based on the IR3109 quad OTA. It uses a BA662 VCA to control the resonance. A second BA662 serves as the voice's VCA proper. As for the 106? The notorious 80017A is really just an encapsulation of three ICs and some resistors. The IC's? An IR3109 and a pair of BA662s! It's the same circuit, just in a smaller package. A lot of people don't realize that when you look at an ordinary IC, most of what you see is packaging; the actual integrated circuit is a tiny bit of silica embedded in the plastic. Roland bought a bunch of unpackaged 3109s and 662s and had someone encapsulate them, and voila, the 80017A was born. Similarly, the Juno-60's DCO circuit: the counter IC that times the DCO, the reset transistor, and the wave shaping circuitry are encapsulated into the much-less-infamous (because it seldom fails) MC5534 in the Juno-106. The voice circuits are, for all practical purposes, the same." So why do they sound different? Check out Sequence 15 for the full post.

Blacet Stock Update 10-15-08

"Almost everything is available to order.

LFO PCBs should be here next week but you can order now.

No kits on the Improbability Drive, only assembled. If you can't wait for the kit to be back in stock, drop me an email--maybe we can deal. (It may be a while before we make any more IDs...).

Speaking of which, here's a video of the ID in action courtesy of Steve Lerner.

Pitch shifting & Amplitude Modulating a Drum Sample with a "Voice Changer" kit

Pitch shifting & Amplitude Modulating a Drum Sample with a "Voice Changer" kit from Isotope Of Me on Vimeo.
"In the interest of learning more about the electronics I use, I put together this simple beginner's DIY electronic kit from Maplin. I modified it slightly, where there should have been a small condenser microphone I put in a wired input so that I can route sounds from the modular and computer through it. This is an example of the (ahem) high quality pitch shifting algorithm you can get your hands on for 10 GBP and what it does to a drum sample. This little battery powered gizmo pitch shifts up or down 3 octaves, amplitude modulates with a square wave and and has what I assume to be a ring modulation mode. I'm using my Doepfer VCA to attenuate the signal."
