basic 65 is a monophonic synth, inspired by the classic 80s home computer, the Commodore 64 and its legendary SID chip. Building on the waveforms and signal path of this famous chip, basic 65 adds further features and options to take things a step further.

The double arpeggiator allows complex versions of that retro 8-bit game sound and the modulation options inspire experimentation via the mod envelope and 2 comprehensive LFOs. Pulse width modulation, ring modulation and oscillator detune/sync are key ingredients in the signature sound. Throw in some pitch drift, bit drift, a sprinkle of dirt and randomisation and you have a wide range of lofi, chiptune, retro-tastic sounds at your disposal.

basic 65 was co-developed with sink, who also made the presets.


  • 16, 8 or 6 bit sound quality.
  • 3 oscs, each with their own ADSR envelope.
  • Oscillators can be sync'd and ring modulated by each other.
  • Pitch envelope modulation.
  • Pitch wobble option, for subtle instability.
  • 2 tempo-sync LFOs to modulate pitch, cut-off and pulse width.
  • LFOs have attack/release curves.
  • Tempo-sync arpeggiator.
  • Flexible routing to state variable filter (LP, HP & BP).
  • Envelopes can be reset or continuous at retrigger.
  • Monophonic or polyphonic option.
  • MIDI learn / MIDI CC support.
  • 128 presets by sinkmusic & WhiskeyPriest.

this is my favorite vst of all time. the sound is so analogue to my ears. i'm reminded of Boards of Canada or Aphex whenever i use this. i am totally in love. i have used many Comodore 64 emulation synths, both free and not, and this one beats them all!


Interface? beautiful. everything is right where i want it. it is very easy to tweak and get the sounds you want. and it has the classic look of 64. even better, in my opinion.

Sound? amazing. i can get glitchy effects/noises, rhythmic whispers and riffs, apeggiated goodness, fat basslines, and drifting analogue pads. in a mix, it stands out.. but not too much so that it takes away from the other instruments.

Features? numerous. while it won't cough up EVERY sound in the sound spectrum, it does more than just emulate a Com 64. with an arp, 6/8/16-bit sound quality, and even individual volume/detune/pulsewidth/ADSR for each of the 3 OSCs, this baby's sound palette is practically unlimited.

Documentation? complete. and while there is plenty of information on how to use this synth, i have never needed to peruse it even once because it is so simple to figure out.

Presets? incredible. a wide variety of awesome presets are packaged with this little 64 beast. basses, sound fx, rhythms, pads - 128 presets is more than enough to get you on your way.

Customer Support? fantastic. i have never needed any support for this, but de la Mancha is commonly found in the KVR forums, and he is a very personable developer. i'm sure if you have any issues with it, he will be more than happy to help.

Value for Money? free. need i say more?

Stability? solid. never had any stability issues in FL Studio 7 on my Intel Celeron PC. this baby is a powerhouse!


So in conclusion: download the basic 64. it's free. it's quality. it's the best free vst out there.
