VAST synthesizer · Mac · for the Kurzweil K2700

KINSPIRATION

The K2700's VAST synthesis on your Mac.

Build K2700 programs layer by layer, hear every change at once on your K2700, and keep the result there.

Coming soon

KINSPIRATION speaks the K2700's own language: programs of up to 32 layers, keymaps, wiring algorithms of DSP functions, envelopes, LFOs, ASRs, FUNs and effect chains, every parameter in the instrument's own units. What you design on the Mac is a real K2700 program.

Turn on the LINK and hear it on your K2700 while you edit. When it is right, store it in a USER slot or export it as a .K27 file.

Inside

What it does

VAST, complete

Up to 32 layers, 106 wiring algorithms, 63 DSP functions and 256 voices.

Modulation everywhere

256 control sources, 7-segment envelopes with loops, LFOs with 46 shapes, ASRs and the FUN equations.

FM and KB3

6-operator FM layers with 32 algorithms, and the KB3 tonewheel organ with drawbars, percussion and rotary.

Effects

107 effect algorithms in insert and aux chains, with a chain editor.

Arpeggiator and sequencers

Arpeggiator, step sequencer, CC sequencer, tempo and TAP.

The K2700's screen

A replica of the instrument's colour display, its pages and soft buttons, for the Keymap, Sample and Global editors.

CONTROL panel

9 knobs, 9 sliders and 9 buttons, named for each program as on the instrument.

Live LINK

Over USB MIDI the program goes to the K2700's edit buffer, and every change follows as you make it.

.K27 in and out

Import .K27 and .P3K files; export programs with everything they use, ready for the K2700.

REPLICATE: from a recording to a program

Drop in a one-note WAV and REPLICATE proposes programs from several sound families (sampled, VA, FM, additive and more), each with a similarity score. Pick one, refine it on the SPECTRUM screen, keep it.

Works with Claude

Describe a sound in plain words, or hand over a recording: Claude writes the program, plays it in KINSPIRATION, measures it and refines it.

Closer

A closer look

DSP CONTROL · MODULATION on layer 1: the pitch row, then PWM, all-pass, wrap and shaper rows, each with its value, tracking and two sources, the algorithm beside them — DSP CONTROL: every row of a layer, its value, key and velocity tracking and two modulation sources. Here ALG 2, four functions in a row.

DSP CONTROL · MODULATION on layer 2: a sync saw oscillator across the four blocks, its pitch and sync offset moved by controllers, LFOs and a FUN — Another layer, another algorithm: a sync saw across all four blocks, swept by controllers, LFOs and a FUN.

DSP CONTROL · MODULATION on layer 4: a four-pole low-pass across the four blocks, its frequency moved by the attack state and two FUNs — A four-pole low-pass on the whole layer, its cutoff driven by the attack state and two FUNs.

The FM LAYER window on FM MAIN: the algorithm drawn as six coloured operators with their ratios, feedback and transpose, and each operator's level, ratio, detune, envelope, rates and levels — FM MAIN: the algorithm and all six operators, each with its envelope drawn.

FM OPER for operator 1: its envelope, its keyboard level scaling, its frequency, waveform and input, and its level and frequency modulation — FM OPER: one operator in full, its envelope, level scaling and modulation rows.

FM LYR: the layer's transpose, detune, feedback and sync, the FM LFO with its shape drawn, and the pitch EG — FM LYR: the layer, the FM LFO and the pitch envelope.

FM INPUT: the alt input from another layer, the keymap's level and the keymap's pitch, each with its sources — FM INPUT: another layer or the keymap into the operators.

FM AMP: the layer's level after the operators, then the output: pan, gain and crossfade — FM AMP: the level, the pan and the crossfade.
