acid-fm1

• A monophonic saw and pulse voice runs through an original saturated four-pole filter with cutoff, resonance, envelope, decay and accent.
• Patterns hold up to 64 steps with notes, rests, accents, slides, per-step probability, one to four ratchets and cutoff locks.
• Independent note, accent and slide loop lengths, swing, four directions, root and scale choice, seeded generation and mutation reshape a pattern.
• Three tempo-related modulators with six shapes, including eight-point curves, route to cutoff, resonance, pulse width, drive, pitch or level.
• Seven distortion modes, a mono feedback delay with stereo taps, chorus and compact ambience finish the sound.
• PLAY starts and stops the pattern, SELECT turns through the sixteen pages, and K1 to K4 edit the four displayed values.
• Live mode plays a last-note-priority voice, ARP switches to a held-note arpeggiator, and REC writes notes into steps.
• SAVE stores the whole patch and pattern in one of four slots, with USB and TRS MIDI carrying notes, transport and clock.
