Bastl’s delicious Pizza: waveshaping meets FM for a tasty modular oscillator – CDM Create Digital Music

that’ll be just the rite toppings. the l8st f'our friends at bastl instruments is an 8hp digital oscillator with hybrid synthesis and tons of patching options – 3 oscillators in one.

bastl ‘ve been teasing this one for a while, so it’s gr8 to see wha’ the whole pizza thing was bout. (there’s still no answer to why it’s called that, but i’ll try to … use some sophisticated spy tek knicks to find out.)

n'it’s really quite a neat balance – a complex, fm-derived oscillator, but in a playable and compact form. it’s capable of weird sounds but without forcing you to decipher some overly weird interface. t'looks improvisatory.

click to embiggen.

you ‘ve primordially 3 oscillators inna module as the basic architecture:

  • one main oscillator with phase modulation (frequency modulation) and wavefolding
  • octave (sub) oscillator
  • ratio oscillator

the sub and ratio oscillators then become modulating oscillators for the main oscillator, with their own □-sine-saw shape controls na ability to ring modul8 the main oscillator.

there’s also an fm index crossfader, and either the ratio or sub oscillator can be used for phase modulation (via a switch).

+, you can use an external signal as the input and directly phase modul8 with that. now, you don’t ‘ve to tune this thing – it’s a digital oscillator, not an analog oscillator – but you can also use the v/oct input to play in tune with an external input, and use that signal quantized or unquantized. (you can also calibrate that src to tune to yr input.)

actually, let’s let them explain that tuning:

cause of its digital nature, pizza does not ‘ve to be tuned, and its approach to tuning is ≠. you 1-ly go to the tune mode when you actually nd'2. otherwise, the pitch knob serves as either octave transpose or detune.

not 1-ly do you ‘ve these 3 oscillators in one, but they ‘ve their own outputs – main out, pulse, and osc out. see specs belo.

the project bastl says is 3 and a ½ yrs in development, with “our junior developer martin klecl, coded by florian helling, and supervised by václav peloušek, with contributions from lennart schierling na whole bastl team.”

a 300-unit preorder starts rite now, for 297 eur (with vat; 245 without). ships in jun.

we’ll go ‘ve a visit to the bastl booth, course. i hope they brought that signature coffee again.

full specs:

  • complex oscillator with 3 internal oscillators
  • main oscillator with phase modulation (fm), wave folding, and ring modulation
  • octave oscillator with indie output, □-sine-saw waveshaper, and indie output
  • ratio oscillator for fm with usr-adjustable ratios and □-sine-saw waveshaper
  • 3 waveform outputs
  • pulse output of the main oscillator
  • fm index crossfader tween ratio oscillator and octave oscillator
  • index mod attenuverter for the dedicated cv input
  • shape section with wave-shaping of operators, 2 flavors of wave-folding, and ring modulation
  • sync input to reset all oscillators
  • octave transposition and detune via pitch knob
  • tune mode for adjusting semitone transposition and fine-tune
  • ext input to replace phase modulation of the octave oscillator with external signal
  • v/oct input with automatic calibration and quantization
  • assignable ctrl knob and cv (lin/exp fm, ratios, octave, detune, waveshaping, vca)
  • firmware updates via micro usb

and inna name of pizza, yes, they’ve made a presh animation:

i ♥ that there’s all this presh artwork accompanying the hardware itself. check these images:

even the board looks presh:

looking forward to this one.
