Desoldering an IC from a PCB

"If you ever wondered how you get an IC desoldered an easy way if you don't care about the IC but want to protect the board, just look here.
Not perfect, but maybe informative enough."

Analogue Solutions Red Square v2

"Giving my Red Square's ringmod the finger... with an assist by Synthesizers.com Q106 VCO.

The cable I am handling feeds into the ringmod 'Y' socket. Reading up on typical ringmod x/y nomenclature will explain what is happening."

Analogue Solutions Red Square v2 Acid

"(Around 1:34 a note is dropped -- that's not the Red Square's doing -- my laptop went into sleep mode and skipped a note.)

Just a demo to see what Red Square sounds like with a patch o' acieeed.

Pretty much just using the top row of the synth, which is internally prepatched. Only patch cable is for allowing midi-to-cv pitch output to slightly mod the filter cutoff.

You'll note that I didn't tweak the resonance. The rez is what I would call "touchy" it goes from rezzy to screaming self-oscillation in just a few degree turn of the knob, so I tend to set it and leave it. Will probably do a mod someday to change that."

EDP Gnat

images via this auction

"Gnats are usually nothing but an annoyance, but in this case, we'll make an exception. The Gnat is a single-oscillator version of the Wasp. It has one digital oscillator and analog circuitry with a basic lowpass resonant filter, envelope with Attack and Decay controls, an LFO which can modulate the pitch or filter, and a built-in speaker. Like the Wasp, it has a very un-playable touch-sensitive flat keyboard with 25 keys. The Gnat also had EDP's propietary control that could be used to link the Gnat to a Wasp or other EDP gear. Like the Wasp, the Gnat also came in three versions. Besides the original, a Gnat Special (pictured above, released 1982) and Gnat Deluxe were released. They had wood panels and a few other changes and the Deluxe used a a standard 3 octave keyboard. The Gnat offers simple and traditional synthesis of analog bass, synth and other useful monophonic sounds. It's designer was Chris Hugget. Specifications: Polyphony - Monophonic Oscillators - 1 DCO (adjustable from 2' to 32'), switchable between ramp, square, enhance, and noise LFO - one LFO with sine, ramp, sawtooth, square, and random waveforms Filter - one low-pass 12dB/oct filter with resonance Arpeg/Seq - None Keyboard - 25 capacitive non-moving touch keys (or 37 standard keys on Deluxe model) Memory - None Control - EDP proprietary digital socket INPUT. MIDI retrofits and some MIDI-CV converters are able to provide control. Date Produced - 1980 - 1983"

"The EPS-1 Electronic Piano and Strings, offers six different LED pushbutton-selected piano voices. A front panel mounted variable key Dynamics control allows the performer to adjust keyboard response and a built-in 3-band Equalizer allows tailoring of sounds; A special Presence boost control produces a totally different sound by variably emphasizing me harmonics portion of me selected voice, depending on how hard notes are played. Also featured are LED pushbutton selected stereo Tremolo and Chorus effects with variable Speed and Intensity controls. The separately articulated Strings section features touch sensitive attack time, making the EPS-1 the first low cost instrument to offer dynamic articulation of strings.

Strings may be used separately or layered with piano sounds. Each string voice features individual note articulation plus overall Attack and Release Envelope controls, me touch sensitive feature may also be fumed off. Volume, Bass and Treble controls, plus LED push button on/off switch complete the Strings section. The EPS-1 also features a special Key Transpose switch, which allows transposing me entire keyboard up and down a fifth from middle "C", a new piano-type damper pedal, me DS-1, which provides effortless sustaining functions for both piano and string voicings. Rear panel: stereo, mono, separate strings and headphone output jacks and tuning control."

Moog 950B Scale Programmer

"Very rare Moog 950-B Scale Programmer."

Anyone know more about these?

Update via elgauchoandres in the comments: "It was a very nice add-on for the modular.

From moogarchives.com:

950B SCALE PROGRAMMER:
Designed to be connected to the 950 Keyboard Controller, the 950B bypasses the 950's equal-tempered interval control, thus allowing for the individual tuning of each note on the keyboard. The 950B consists of sixty independent manual controls, each of which varies the magnitude of an interval between two successive voltage levels on the 950. Tuning is continuously variable from 0 to 2 semitones..
