KORG Synthe-Bass

via this auction.
Details:
"This is a vintage analog synthesizer released around 1975 (Around the time of the Mini and Maxi Korgs). It's got 5 waveform choices a huge Sine, a buzzy Square, Fat Triangle, More buzzy Square, and then a Phaser setting that makes a sound that is similar to an old Moog Prodigy. It also has a "traveller" (filter cutoff). It is a very small and light Synth/ keyboard (17 keys) that puts out great analog bass tones"


Update: There was also a pedal version that looks like it could work as a desktop unit which you can see in this post.

Update via the comments: "RE: the update: the synthpedal isn't a pedal version, it lacks the VCO and more. The synthepedal is just a env follower VCF, an amazing filter but not a bass synth"

KORG Micro Preset M500 SP

Click here for shots via this auction.

Update: Some interesting bits on the M500 just in via The Most Underrated Synth post.
"It has one oscillator, 2 2-pole resonant LP filters (one for the synth preset, one for the brass preset), and four fixed (organ-style) filters. The 2 filters have VCAs built in, and each of the fixed filter circuits had its own VCA and (fixed) envelope generator. The brass voice and synth voice also had their own envelopes. The envelope attack and release controls affected the synth and brass VCA and VCF.

They could afford 6 VCAs because, for a fixed-voice, fixed-envelope monosynth, they could get away with one-transistor VCAs and RC (NO active component) envelopes, and the VCF/VCA chip I imagine was used in other synths as well.

OMD used this synth a lot on their first few albums. You can recognize it easily in their stuff before they got into samplers, which you can also recognize (Dazzle Ships onwards)"

resonant bandpass filter and dual distortion

"this is a new original analog design ( though inspired by the single bands of the korg P3100 filter ) with a few different things going on. the signal path flows like this - buffer - very high gain preamp with switchable clipping distortion - resonant bandpass filter with variable resonance that can self oscillate at higher frequencies and has an adjustable and switchable frequency range - variable heavy breakup distortion - and a violet ( or blue - i ran out ) level indicating led"

"also Ty of dispyz.com has an enormous data recovery bill on the way due to a head crash ( 3 years of work gone ) so he is "regrettably" selling off his Amnesio SL-0.131 prototype. he said just original cost and free shipping i think. you can get in touch with him via email at: dispyz (at) dispyz.com or through his MySpace site he will probably also be posting this in the forum so you can ask him questions if you want ( its like new ) but be nice because he’s using a borrowed PSP the get online, crazy. just thought i would give him a much needed hand and see if anyone is interested. the 131 has 2 lo-bit looping samplers and a passive analog ring modulator ( its a mingrod minus the octave up) all in one box."

10-band Panned Equalizer in Csound

via thumbuki in the comments of this post:

"I built a 10-band equalizer in Csound where each band is panned individually, using phase offset lfos similar to the quadrature function generator.

Here's the snippet of code that creates the phase offset lfos:

klfo1 table ( klfo + 0.0 ) * ilength, iwave, 0, 0, 1
klfo2 table ( klfo + 0.1 ) * ilength, iwave, 0, 0, 1
klfo3 table ( klfo + 0.2 ) * ilength, iwave, 0, 0, 1
...
klfoA table ( klfo + 0.9 ) * ilength, iwave, 0, 0, 1

The floating point numbers set the phase for each lfo. Phase is normalized to a range of 0 to 1, so a value of 0.1 equals 36 degrees and 0.5 equals 180 degrees.

The full code can be found here, in instr 112."

Hohner Electronium

Click here for shots via this auction.

Details (Google translated from German):

"The Hohner Electronium pi is an old key board from the year 1950 that the concept almost resembles a Clavioline. The basic sound of both instruments is however very different, since the tone generator of the Electronium pi produces a saw tooth wave shape, while it is with the Clavioline a square wave form. Roughly expenditure-press sounds the Elektronium pi rather like a trumpet and the Clavioline rather like a clarinet. The equipment is developed complete in tube technology and offers from tubes admitted sound. One can call these only extremely alive, warmly and nobly. It is one of the instruments, with which the well-known composer Karl Heinz stick living invented and justified the electronic music in the year 1954 in Cologne Studio of the WDR."
