Manuals for Ahornberg-VCV-Modules

Tape Recorder

An emulation of a Microcassette recorder.

Tape Recorder

How to use it (click on the image below to watch the video):

Tape Recorder Manual

Transport

There are buttons for play (both directions) and fast forward/rewind.

[Ctrl] + [fast forward/rewind] jumps to the next/previous loop point or to the end/start of the tape.

[Shift] + [Ctrl] + [fast forward/rewind] jumps to the end/start of the tape.

Record is always on!

As long as one of the play buttons is on, the machine will record incoming audio to the tape.

Scratching

For scratching the reels, the play and pause buttons have to be on.

Transport Input

An impulse toggles the pause button.

Transport Output

Play forward gives 5 Volts, play backwards gives -5 Volts.

Tape Speed

The speed of the playing tape can be changed in a musical way by providing CV-Pitch (1 V/Octave) input and output.

Loop Mode

The tempo settings (BPM and Beats/Bar) provide the basic time measurements for the loop settings.

Loop On/Off

As long as loop start and loop end show the same value, loop mode is turned off.

Loop inputs

Loop start and loop end points can be changed by providing a CV signal (1/12 Volts per Bar). This signal will be added to the corresponding knob value.

Equal Division

Module for VCV-Rack to convert Note CV in Standard Western Tuning (12ed2 = 1 step equals 100 cents) to several Equal Division Tunings.

EqualDivision

Fine Tune

Makes it possible to compress or stretch a tuning in a range from -3 to +3 percent.

Display

Shows the actual selected tuning.

Interval

The yellow digit or fraction on the right side stands for the interval the tuning is based on. Possible values are

  • 9/8 .. a just intonated Major Second (aka. Major Whole Tone).
  • 8/7 .. a just intonated Supermajor Second (aka. Septimal Whole Tone or Dimished Third) .. 231.174 cents
  • 7/6 .. a just intonated Subminor Third (aka. Septimal Minor Third´or Augmented Second) .. 266.871 cents
  • 6/5 .. a just intonated Minor Third .. 315.641 cents
  • 5/4 .. a just intonated Major Third .. 386.314 cents
  • 4/3 .. a just intonated Perfect Fourth .. 498.045 cents
  • 3/2 .. a just intonated Perfect Fifth .. 701.955 cents
  • 2 .. an Ocatve .. 1200.000 cents
  • 3 .. a Tritave or Duodecime (an Octave and a just intonated Perfect Fifth) .. 1901.955 cents
  • 4 .. a Double Octave (two Octaves) .. 2400.000 cents
  • 5 .. a Just Major 17th (two Octaves and a just intonated Major Third) .. 2786.314 cents
  • 6 .. two Octaves and a just intonated Perfect Fifth .. 3101.955 cents
  • 7 .. the 7th Natural (two Octaves and a just intonated Subminor Seventh, aka. Harmonic Seventh) .. 3368.826 cents
  • 8 .. three Octaves .. 3600.000 cents

ED

The green letters ED stand for Equal Division.

Number Of Equal Steps

The yellow digits on the left side display the number of equal steps the interval is divided in.

9 x Note In/Out

Nine vertically orientated pairs of Note CV inputs and outputs provide the ability to tune 9 x 16 = 144 different signals simultaneously using only one module.

CV-Frequency Shift

A linear frequency shifter for CV note pitch signals.

CV-Frequency Shift

The input is taken as a CV-pitch value and is transformed to frequency in Hz, e.g. 0 Volts input = note C4 = 261.63 Hz, then let’s say + 108.36 Hz will be applied, this results in 369.99 Hz = F#4. But if I would have taken C5 = 523.26 Hz as input, by applying the same + 108.36 Hz leads to 631.62 Hz and this frequency lies between D#5 and E5.

So it is a linear frequency shift, of course only on the base frequency, not on overtones that might be produced by VCOs afterwards. The intention is to use VCOs that produce sine waves. The module can calc 9 x 16 = 144 values simultaneously, so enough to build complex sounds with inharmonic overtones based on sinewaves.

This module complements the Harmonizer module.

X-Glide

Cross-glide between 2 notes.

X-Glide

This module needs polyphonic input to work. The transition from one pitch to another is proportional to the difference between volume of note one and volume of note two.

Note Range

With the 2 knobs you can select the lower limit (left knob) and the upper limit (right knob). In between, cross-glide from one note to another will happen.

When the value of the left knob equals the value of the right knob or is larger than the value of the right knob, the note range is inverted and the red light between the 2 knobs goes on. Now there are 2 note ranges, one from the bottom (C0) to the value of the right knob, and another note range from the value of the left knob up to the top (G10).

Interval Range

With these 2 knobs you can select the smallest interval (left knob) and the largest interval (right knob) in semitones, where coss-glide will be applied.

When the value of the left knob equals the value of the right knob or is larger than the value of the right knob, the interval range is inverted and the red light between the 2 knobs goes on. Now there are 2 interval ranges, one from 0 semitones up to the value of the right knob, and another interval range from the value of the left knob up to 127 semitones.

Pedal / Gate

When the input "Pedal / Gate" is connected, cross-glide only works on a high gate value.
