"MIDI programmable Oberheim Matrix Module loaded with 1000 presets. Each of its 6 voices have two DCO's (digitally controlled analog oscillator), a low pass filter, 2 VCA's, 3 envelope genertators, 2 LFO's, and 2 ramp generators. The Matrix 1000 provides an excellent source of pads, textures and ambient sounds. Made in the USA. Some rack rash on top and bottom of chassis."
"Does it get any better than this? An immaculate example of an original analogue Oberheim OB-8, looking like its just emerged from the small LA factory in 1984 39 years ago. No mods. No hatchet repairs etc, with MIDI, new Fatar keys and (copy) owner's manual. Arrived from Switzerland March 2023, double-checked/serviced/calibrated by our TOP OB specialist...now back with us in the E.Midlands. There are now some wicked sounds on board.... be warned, this synth sounds staggeringly good..."
"Deftaudio Two Channel CV Gate Attenuator for Eurorack Two channel gain and max voltage passive attenuator with three options available:
Basic version, two channel with 3.3V, 5V limits, precise adjustment and LED control Indicator version, two channel with 3.3V, 5V limits, precise adjustment with a vintage arrow indicator per channel Voltmeter version, two channel with 3.3V, 5V limits, precise adjustment with a single digital LED voltmeter Description:
This is simple and efficient board to adjust voltage level when interfacing between Eurorack gear and to the outside world. It's specifically important for Gate levels, which exceed typical voltage level of 3.3V or 5V and go all the way up to 12V. While modular gear typically designed to handle those voltages, other instruments such as sync or arp inputs on vintage synths may not have a protection at all.
This board designed in mind with three modes of operation which are not available in other products:
3.3V logic limit. This mode is protected by a Zener diode and meant for interfacing to 3.3 logic gear, such as microcontrollers, Arduino, Teensy, etc. 5V logic limit. This mode similarly has a Zener diode circuit for 5V logic of the majority synthesizers sync, arpeggiator and other various trigger inputs. Attenuation. In this mode multi-turn potentiometer sets the attenuation ratio. While two other modes set the max voltage limit, in this mode the output voltage is linearly scaled down to the attenuation ratio set. Purchasing options:
PCB only: Only PCB board is included, other parts, such as connectors, diodes, resistors and LEDs are sourced by a buyer. DIY Kit: Comes with all parts including arrow indicators or digital voltmeter per selected option. Soldering is required. Assembled board: this option is NOT planned at the moment."

The sound comes entirely from the App GSi Mini Orchestra running on the iPad. No sequences, entirely played live with two hands on that 61-key controller."
"The Hollasynth four-channel scanning VCA is a version of Jurgen Haible’s Interpolating Scanner idea, in 4U Serge-compatible format, complete with a beautiful front panel by Loudest Warning
It is a four-channel voltage controlled crossfader. As the scan CV is swept from 0V to 5V, the mix output fades from channel 1, through a mix of channel 1 and 2, to channel 2, then fades to channel 3 and finally channel 4. In addition to the main mix output, there is an individual output for each channel. Front panel knobs provide an offset and attenuversion on the scan CV.
The gain of each channel is also individually controllable, so the module can be used as a four channel VCA as well. A switch allows the scanning control to be disabled so that only the VCA CV affects channel gain. Finally there are attenuator for the gain CV and initial gain knobs on the front panel.
What can I do with it? Probably more than I can! But try some of these:
Crossfade between the wave shapes of a VCO for voltage-controlled morphing, e.g. from sine to saw to triangle to square and back. Like this. Crossfade between up to four audio sources under voltage control. Like this. Voltage controlled CV mixing. The inputs and outputs are DC coupled so you can use the module to mix and morph between CV sources Voltage controlled signal switching. By appying stepped CV to the scan input, e.g. from a sequencer, you can switch between signals rather than fading… if you get the CV set up just right! Like this Audio Waveshaping. Patch fixed voltages or LFOs or whatever you like into the signal inputs. Send an audio rate 0-5V sawtooth into the scan CV. Use the mix output as am audio signal. Like this. Or like this. (Thanks, Loudest Warning!) How does it work? The scanner contains four linear VCAs, one per channel, based on the LM13700 IC. Each VCA is controlled by the sum of two CVs: the direct VCA CV and the scanning CV. The scan CV is provided by a version Don Tillman’s beautiful scanner implementation, used with his kind permission. (But please don’t bug him if you have issues with the module!)"
