a UCApps.de project

MIDIbox SID is a non-commercial & "DIY-only" project. Beside of the common SID functions (three oscillators, triangle/saw/pulse/noise and mixed waveforms, independent envelope generators for the amplitudes, sync & ringmodulation, 12db multistate low/band/highpass/notch filter)

it features:

  • 2 additional envelopes with optional non-linear curve which can be assigned to Pitch, Pulsewidth and Filters
  • 6 additional LFOs with different waveforms which can be assigned to Pitch, Pulsewidth and Filters
  • Fine Tuning
  • Pitch Bender
  • Portamento/Glide function
  • Delays
  • optional Oscillator Synchronization
  • Arpeggiator (a SID *must* have an arpeggiator ;-)
  • Poly, Mono and Legato Mode
  • seperate keyboard zones for each voice (key splitting) allows to play voices seperately
  • Free controller assignments to Modulation Wheel, Velocity and Aftertouch
  • wave and CC sequences which allow more percussive sounds (Wavetables)
  • the wavetable sequencer can be combined with the arpeggiator in order to realize complex textures
  • LFOs, Envelopes, Wavetables, Arpeggios optionally syncable via external MIDI clock
  • up to 8 CV outs with 12 bit resolution (in experimental state)
  • OS independent SysEx editor based on JSynthLib
  •  Bank Sticks with 128 sound patches per stick
  • can be used as .sid file player
  • optional minimal controll unit (Step A)
  • the possibility to control up to 4 SIDs (Step B)
  • a complete control surface (Step C)

This was my MBSID step A

Also check out the Pong game I coded for the MBSID.

download it and watch a quicktime movie in the download section

I really love my SID
an this wonderfull project from TK!!!
Highly recommendable.
