De La Mancha has released basic 65 – a monophonic synth, inspired by the sound of the Commodore 64 – as freeware.

Building on the waveforms and signal path of this famous chip, basic 65 adds further features and options to take things a step further.

Features:

• Monophonic synth in VST format for Windows based hosts
• 3 oscillators with pulse, saw, triangle and noise waveforms
• Pulse width can be modulated by envelope or both LFOs
• Each oscillator can be sync’d to another and/or ring modulated by another
• Each oscillator has its own ADSR envelope and can be routed to filter individually
• Resonant filter with low pass, high pass, band pass and notch modes
• 2 tempo-sync Arpeggiators in series for complex arp sounds
• Arp tempo, range and note length can be adjusted
• Modulation envelope can control pulse width and pitch of individual oscillators as well as filter and dirt
• 2 tempo-sync LFOs with wide range of waveforms, including random
• Both LFOs can control pulse width and pitch of individual oscillators
• One LFO also controls filter and dirt, the other can modulate the depth and speed of the first LFO
• Envelopes are non-linear and can be retriggered from zero or smoothed on each new note
• Pitch drift models instability with variable depth and frequency
• Options for 4, 6, 8, 12 or 16 bit audio with randomising feature
• Developed with SE 1.1, so no problems with multiple instances
• 128 presets by sink covering arps, leads, bass, drums and lofi sounds
