New EQ Board for the Rhodes Chroma

via the excellent Rhodes Chroma site where you'll find full details.

"Why an new EQ-board?

Well, most mixers, FX devices and so on nowadays have balanced inputs/outputs. So why shouldn't such an old baby like the Chroma get that feature too? On the other hand the nearly obsolete CEM3360 VCAs on the EQ-board should better used as a replacement part on a faulty DVB as substituting them isn't an easy attempt for some reasons. The circuit is simple: a quad VCA SSM2164 (Z1) replaces the two dual CEM3360 VCAs. It's a current-in current-out device with 33mV/dB controls. Note: This not an OTA! The core looks more like a multiplier (see Figure 1). The (audio) voltages 0-3 coming from the CMB are converted into currents by the 30K resistors. The 510Ohms 470pF series pad from input to ground prevents oscillation."

GAMEBOY, ARDUINOBOY 3 OSCILLATOR SYNTH

YouTube Uploaded by sammybartl on Jul 8, 2011

"a poject ive been working on.
only just in working stages, not fully working! but nearly hope you see what im getting at with it :)
plan was to make an oscillator part of a modular synth out of gameboys (ie 3 seperately adjustable oscillators). so used arduinoboy software and designed an oscillating part for the synth!

this is it!
hope to build more of the modular synth later on at the back i have made patches for cv to effect pitch and envelope, see what happens!!
also i will show it in greater depth on my blog :----

hope you enjoy :)"

Roland SH-5 analogue monosynth

via this auction
"Rare, vintage Roland mono synth dating from 1976.
Great sound with lots of sonic personality and features.
The features:
2 oscillators with 32 / 16 / 8 / 4 / 2 range settings with fine tune on vco 2.
Triangle, sawtooth, square and variable square waveforms for both oscillators.
PWM modulation possible for both oscillators.
Oscillator sync with weak and strong settings.

2 low frequency oscillators:
LFO 1 has two shapes, up and down ramp/ sawtooth. LFO 2 has 3 waveshapes, triangle, sine and square wave
There is both pink and white noise source.
There are two resonant filters, the first is a multimode filter with 3 modes, the low pass is a 24 db diode filter much like the EMS Synthi/ VCS3, plus additional band pass and high pass modes.
The second filter is a classic 6 db band pass that sounds great.

There are 2 envelope generators an ADSR and an AR, both envelopes can be triggered by multiple sources.
There is a sample and hold generator and a ring modulator.
Great routing capabilities, each section can be modulated by different sources using switches at the top of each section.
The mixer has individual sliders for volume for both oscillators, noise, ring modulation and external input, each source in the mixer can be routed in different ways, either passed through either filters, both filters together in parallel or sent directly to the vca.

Excellent external input processing possibilites with High/Medium/Low input sensitivity switch settings on the rear.
Low level (microphone) / Medium (electric guitar) / High (keyboard)
Inputs can be fed through the ring modulator and the filters/ vca.
Finally the vca can be triggered by has a hold setting and a stereo output with panning knob.
Can be controlled via CV and gate with input / output jacks on the rear.
The synth is capable of a large range of sounds and has great possibilities for processing external input."
