### What’s new?

#### … in v2.6.3?

- added stereo to Adje

#### … in v2.6.2?

- bug fixes for Funs

#### … in v2.6.1?

- optimization for Ad, Adje and Sjoegele
- renamed the “buffer” input to “amps” in Ad, Adje and Bufke and Ad’s “fund” output to “root”
- in Sjoegele:
  - added θ = 0 outputs
  - added friction
  - removed θ inputs
  - changed parameter ranges

#### … in v2.6.0?

- new module: Sjoegele.
- in Ad:
  - More accurate computation for the sine waves.
  - Removed fundamental wave shape from the context menu and added automaic octave transposition.
  - Slight change to the reset button and input, such that oscillator sync works now.
- in Ad and Adje:
  - Changed some of the knob marker labeld to icons (instead of numbers).
  - Added a comb filter, controlled by the delay parameter, when the ‘→ buffer’ jack is disconnected.
- in Bufke:
  - Added connection indicator.
- in Ad, Adje and Bufke:
  - Reworked the mapping of the delay knob.
  - Added a light on the reset button.
- in Funs:
  - Changed the mapping of the three parameters, such that it avoids most of aliasing.

#### … in v2.5.0?

- new modules: Adje, Bufke and Funs.
- Changed Ad’s front panel slightly: moved some things around to make it similar to Adje, and changed the numbers for the tilt knob to icons.
- Converted this manual from PDF to HTML.

#### … in v2.4.1?

- The Σ outputs are in general a bit hotter (but still within ±5 V), due to a change in the normalization procedure.
- Optimization, by reducing the computation rate for the amplitudes of the partials.
- Extended the range of the tilt parameter: from minimum –2 to –∞.
- Added the quantize stretch to harmonics mode.

#### … in v2.4.0?

- Added a spectrogram display.
- Still, it was possible to make the front panel got more compact (12HP) by

- combining the lowest partial and tilt parameters into one parameter,
- moving settings to the context menu,
- getting rid of the buffer CV attenuator/amplifier,
- getting rid of the balance knob (this is replaced by detecting the connection at the buffer CV input),
- getting rid of the octave knob (this is replaced by the pitch quantization settings),
- rearranging.

- Changes in the CV buffer section:

- Added random mode.
- Added the clock input.
- Reworked the delay knob. The left-hand side is replaced by the ‘high → low’ mode.

- Reworked the left-hand side of the sieve knob. Basically changed the order.
- Added reset trigger input.
- Reworked the normalization of the amplitudes, such that the output audio is in some cases a bit louder.
- Reworked the stereo section: the lower partials are panned less than the higher ones now. And the continuous width parameter is reduced to three options.
- Added pitch quantization and reset modes.
- Added left/right channel flipping.

#### … in v2.3.0?

- The CV buffer section is reworked. The most significant bit is that there is now a large buffer which runs at audio rate. Now one can send snappy envelopes into it, which are replayed without any smoothening.
- More compact front panel,

- by replacing the auxiliary oscillator section with only the fundamental output,
- getting rid of the stereo width and balance CV inputs, because I consider those `set and forget' parameters,
- getting rid of the amp parameter, since the new CV buffer section can take this role when the delay time is set to 0.

- Got rid of the change of v2.2.1. I didn't like the clicky sound when turning the stretch knob.
- Added the reset button.
- Changed some knob ranges.

#### … in v2.2.1?

- The phasors can’t drift any more in quantized stretch mode.

#### … in v2.2.0?

- a different, generally more efficient algorithm computing the sines. This algorithm can cause some phase shifting after running a while, though.
- The CV drawer works differently.
- Some parameters are renamed.
- Some of the knob mappings have changed.
- Got rid of a few attenuverters.

#### … in v2.1.0?

- the CV drawer
- the ‘sieve primes’ mode
- bug fix
- some knob mappings

### To do:

- more optimization
- for Funs: fine-tune the parameter space: find a better balance between non-aliasing and maximum possibilities
- for Ad: remove clicking on reset
