Ports of some of Mutable Instruments (tm) oscillators to the Korg prologue multi-engine.
See releases for latest binaries.
| Name | Oscillator | Shape operation |
Shift-shape operation |
|---|---|---|---|
mo2_va |
Pair of classic waveforms | Shape | Pulse width |
mo2_wsh |
Waveshaping oscillator | Amount | Waveform |
mo2_fm |
Two operator FM | Modulation index | Frequency ratio |
mo2_grn |
Granular formant oscillator | Frequency ratio | Formant frequency |
mo2_add |
Harmonic oscillator | Index of prominent harmonic | Bump shape |
mo2_wta-mo2_wtf* |
Wavetable oscillator | Row index | Column index |
* Due to the 32k size constraint in the multi-engine the Wavetable oscillator is split into 6 oscillators with 4 'rows' each.
In the Multi-engine menu you can find additional parameters for the oscillators.
Parameter 1 is oscillator specific and controls whichever parameter is not mapped to Shape or Shift-shape
Parameter 2 sets the mix between the oscillator out and aux.
Parameter 3 sets the Shape LFO target according to the table below:
| LFO Target | Parameter | Notes |
|---|---|---|
| 1 | Shape |
|
| 2 | Shift-shape |
|
| 3 | Parameter 1 |
Not implemented for Wavetable oscillator |
| 4 | Parameter 2 |
For more information please read the excellent Mutable Instruments Plaits documentation.
Many parameters 'neutral' settings are in center position, such as va Detune or fm Feedback, however the prologue defaults all parameters to the lowest value, hence get used to going into the menus and set the first parameter to 50% when instantiating the oscillator.
Physical modeling synthesis
| Name | Oscillator |
|---|---|
mod s |
Strike exciter with modal resonator |
| Parameter | Parameter | LFO Target | Notes |
|---|---|---|---|
Shape knob |
Resonator position | 1 | Position where the mallet strikes, has a comb-filtering effect. |
Shift + Shape knob |
Resonator geometry | 2 | Geometry and stiffness of resonator. Set to 25-30% for a nice tuned sound. |
Strength menu |
Strike strength | 3 | Mallet strength, high values causes the strike to bleed into the resonator output. |
Mallet menu |
Strike mallet | 4 | Type of mallet, over 70% is bouncing particles. |
Timbre menu |
Strike timbre | 5 | Brightness/speed of the excitation. |
Damping menu |
Resonator damping | 6 | The rate of energy dissipation in the resonator. High values cause long release effect. |
Brightness menu |
Resonator brightness | 7 | Muting of high frequencies |
LFO Target menu |
multi-engine Shape LFO target |
Sets which parameter is modulated by the Shape LFO (see LFO Target column) |
For more information please read the excellent Mutable Instruments Elements documentation.
Due to compute and memory (32K!) limitations in the prologue multi-engine quite a few short-cuts had to be taken:
- Only the Strike exciter is used
- Sample-player and Granular sample-player mallet-modes did not fit in memory
- Resonator filter bank is reduced to 24+2 filters from 52+8
- Resonator filters are recomputed one per block instead all-ish every block
- Samplerate is 24KHz vs 32KHz in Elements
Sounds pretty great IMO but go buy Elements for the real experience!
When you first select the oscillator it will make no sound, all parameters are at 0%! Increase the Strength and Damping parameters until you start hearing something.
Try a nice pluck:
| Parameter | Value |
|---|---|
Shape |
50% |
Shift + Shape |
30% |
Strength |
90% |
Mallet |
45% |
Timbre |
45% |
Damping |
70% |
Brightness |
45% |
- The prologue Sound Librarian tends to timeout when transferring the user oscillator, however the transfer is still complete. Try adding the user oscillator one at a time and Send All / Receive All for each oscillator.
