Developer Andrew Stroev shared this preview of Synchrotron, a live audio engine built in Python.
“Synchrotron is an audio engine I’ve been building from scratch over the past year,” notes Stroev. “Finally I have something semi-presentable to show the world!”
Synchrotron is all of the following:
Eternal Engine shared this hand-on demo of the Apparatus Tube Synthesizer.
The Apparatus Tube Synthesizer is described as ‘The first duophonic synthesizer based on vacuum and gas-filled radio tubes.”
Features:
Kenoton rectifier power supply
Audio path based entirely on radio tubes
Two independent thyratron oscillators with quartz frequency stabilization, which ensures frequency accuracy throughout the entire operating range
Voltage-controlled second order filter with the possibility of self-oscillation and overdrive
Voltage-controlled amplifier, based on the traditional schematic of tube opto compressors
Triode asymmetric overdrive
Analog VU meter
CV / Gate inputs to control the oscillators pitch (OSC-1, OSC-2 CVs), filter cutoff frequency (VCF CV) and amplifier amplitude (VCA CV)
External Input for signal processing from external audio devices
velocity-sensitive ADSR envelope generator with two trigger modes
Clock synchronizable low-frequency oscillator with retrigger option and smooth waveform morphing: saw-triangle-reverse saw in triangle mode or pulse width modulation in square wave mode, sample & hold
Auto and continuous modes of portamento / legato
Monophonic and duophonic mode
Responds to Control Changes Pitch Bend, Mod Wheel, Velocity
Channel switching with the Learn button
Galvanic isolated PC connection port
Powerful headphone amplifier, compatible with low impedance load

The Apparatus Tube Synthesizer is available for $1,999.
