"Yes. That's my sister in the background. Sorry the sound quality is bad. The kick sounds crunchy."

"Instructions for turning a mug of tea into a Theremin:
1 Prepare some tea
2 Expose the L/R leads on an 1/8" cable
3 Immerse leads in tea
4 Plug cable into audio input
5 Start up max/pd/processing/etc. and average every 735 samples (882 if you're in Europe/running on 50Hz)
6 Scale value and drive oscillator

(The tea should not be neglected, be sure to drink it once you're done making noise.)

My camera's been acting funny, hence the jitter.

Moog Source

via this auction

"The Moog Source is a 2-VCO, micro-processor-controlled, programmable monophonic synthesizer, with 16 memory locations, and a 3-octave, 37-note (C-C) keyboard.

It features an arpeggiator and a digital sequencer with memory for two seqences of up to 64 notes.

The Source was one of the first to use digital parameter access for programming, a method now commonly found in today's synthesizers, using membrane switches, a two-digit LED display and a single data knob.

Both VCOs have three available waveforms (sawtooth, triangle, and pulse; with pulse width modulation) and three available octaves (32', 16', and 8'). VCO2 can be detuned at fixed intervals and it can be also synced to VCO1.

The mixer section features levels for VCO1, VCO2 and Noise.

The VCF (24dB/octave) has parameters for keyboard tracking (off, 1/2, and full), cutoff frequency, resonance, and contour (Moog's word for envelope) amount.

There are two ADSR envelope generators, one for the VCF and one for the VCA. The envelopes can be set in single or multi trigger modes. The LFO (triangle and square waveforms) can be routed to the VCOs and the VCF.

The Source also features a sample-and-hold which can be routed to the VCF. To the left of the keyboard is the pitch bend and the modulation wheel, along with two octave-switching buttons.

These and a volume knob are the only dedicated controls. On the back panel are the audio out, cassette interface, a pitch knob (for fine tuning), and CV and S-trigger inputs and outputs.

The 16 factory pre-sets are: Lead 1, Lead 2, Horn, Flute, Clav Bass, Vibes, String Bass, Harpsichord, Organ, Trill Voice, Taurus, Synthevox, Sax, Wind, Snare Drum, and Lead 1 (duplicated here so that if you wanted to, you could use this extra slot to move patches around). Programs are saved and loaded via a cassette interface."

"Serial number is 6760 and it has the original version osc board. The date of manufacter is written on the metal plate behind the front panel as 1/29/75."

CORON DS7

via this auction

"An infinitely tweakable array of electronic percussion sounds are available from sub bass kicks to searing filter sweeps with seven knobs for LFO rate, decay length, Mode/timbre, VCO, sweep depth, intensity and volume. The synth is built into a sturdy enamelled metal box and features a clamp for mounting on the rim of a drum."
