In the next few days the first module of the dsp micro modular line will come up on the http://www.dspsynth.eu site.
This line consists of single DSP chips accepting analog signals and made for DIY builders.
The other chips in the line will be the dsp-Vx, a DCO/FM/Wavetable oscillator and the dsp-Ax, DCA/Chorus/Flanger chip.
The dsp-Mx features a +24db 4-pole ladder filter with cutoff and resonance.
The filter is multimode and have selectable LP, HP and BP modes.
It’s controlled through 0-5v CV inputs or MIDI-CC messages, simultaneously.
Input audio is analog -+2.5v with a 96KHz samplerate and output is 16-bit PCM.
Yes, it can be used equally well with MIDI sequencers or analog sequencers. The multimode ladder filter of your dreams.
The DSP chip is a TSSOP-28 but the kit is delivered with it soldered on a breakout board. As simple as the dsp-G1 so it’s for anyone to play with.
You can use it with any audio, synth or VCO/DCO signal.
And the price?
Around $70, cheap for a DIY DSP multimode filter.
Make sure you order one of these.
