Developer Jan Ostman has kicked off an IndieGoGo project to develope the DSP-G1 synthesizer – a DSP-based synth that’s designed as “a tribute to analog synthesizers of the 70’s and 80’s”.
- The dsp-G1 is a computer model of an analog synthesizer, running with a sample resolution of 44.1KHz and 16-bit. It reads the parameters from the front panel knobs and calculates the sound output. It is played through a MIDI-IN connection.
- It features a 3-DCO variable waveform oscillator, 18dB Lowpass filter with resonance, 2 Envelopes and 1 LFO. That adds up to 17 frontpanel realtime knobs.
- The waveform can be seamlessly morphed from Sine, Triangle, Pulse to Saw.
- There is also a Wrap setting for additional harmonics.
- The 18dB resonant lowpass filter sounds very realistic and selfoscillates at high resonance settings.
- It’s 5-Note paraphonic meaning that it can take 5-key chords but they are all routed through single filter and amp envelopes.
- All internal calculations are done at 32-bit integer resolution and output at 16-bits.
- The dsp-G1 is a standalone synthesizer and requires no computer to play.
- Just MIDI input from a keyboard or sequencer.
Here’s an audio demo:
“The great sounds from Roland, Sequential Circuits, Oberheim and Moog can once again live in the form of Analog Modeling on microcontrollers and dsp-chips,” says Ostman. “So I have written the analog algorithms to recreate the sound of the past.”
Here’s another audio demo:
The DSP-G1 is available to supporters of the project for $200. Details on the DSP-G1 are available at the project site.
