# Abstractions for Puredata

This is a collection of abstractions that I have made for Puredata. I use

the Pd convention for adding a trailing tilde (~) to all objects, that

output or process audio. A lot of objects have accompaning help patches.

For all abstractions to load without any error you need the following

libraries, available via deken:

- iemguts

- cyclone

- zexy

## Effects and Mixing (fx)

`[bitcrusher~]`: simple bitcrusher effect.

`[distortion~]`: simple distortion effect.

`[normalize~]`: normalizes the sound and removes offset.

`[pan~]`: equal volume pan for mono.

`[pitchshift~]`, `[pitchshift2~]`: simple pitchshifter, each with its own

residual effects.

`[vol-env~]`: 16 step volume envelope with bypass.

`[waveshaper~]`: render incoming sound to base sounds.

## Glue objects (glue)

`[bangonce]`: outputs only one bang, if the inlet receives a series of

1s. Useful for filtering MIDI data or data coming a comport object like

an arduino.

`[between]`: outputs a random float between two pre-defined values

`[bpmtoms]`: converts beats per minute to milliseconds for each beat,

inverse of `[mstobpm]`.

`[integral]`: integrates float values.

`[mstobpm]`: converts milliseconds for a beat to beats per minute, inverse

of `[bpmtoms]`.

`[mstofreq]`: converts milliseconds to a frequency.

`[note-vel-filter]`: filters a stream of MIDI data to only capture MIDI on,

off and velocity.

`[rec_play_switch]`: two switches for starting recording and playing loops

for `[note-vel-looper]` and `[sample-looper~]`.

`[s2f]`: converts symbol atoms to float atoms.

`[shift-router]`: routes input to one of six outlets with another input

for switching the outlets, useful for usage with push-buttons on an

arduino etc.

`[switch-bang]`: outputs bang alternatively on two outlets when receiving

a bang.

`[switch-matrix]`: routes inlets to outlets. Rows correspond to outlets, 

columns to inlets, so the toggle in row 1 column 2 routes the input from inlet 2 

to outlet 1, e.g. useful for toggling synchronization of `[sample-looper~]` instances.

Can be initialized with the number of inlets and outlets with up to 15, defaults to 4.

`[switch-spigot]`: outputs 1 and 0 alternatively on the two outlets, useful

for switching two spigot objects.

`[symbollen]`: gets the length of a symbol atom.

`[timer-to-freq]`: measures the time between a bang on the left side and

the right side and converts the timespan to frequency.

`[trigger-filter]`: filters a stream of 0s and 1s and only outputs a value

when a change is occuring.

`[unwrap]`: wraps around values at specified lower and upper bound, e.g.

useful for rotation data.

## Looper objects (loopers)

`[breakbeat~]`: loads a stereo sample of 8 beats length, slices it and plays 

it back as a breakbeat with adjustable playback speed and pitch. 

`[live-sampler~]`: records a sample and play it back as loops with MIDI notes.

Pitch of recorded loop is set to note 60, contains ADSR envelope, modulation

of playback pitch.

`[live-sampler-box~]`:  a combination of `[live-sampler~]` and `[sample-looper-box]` 

`[note-vel-looper]`, `[note-vel-looper-box]`: records and plays back MIDI loops

with adjustable start and stop, can be synchronized with other instances

of itself and `[sample-looper~]` instances.

`[sample-looper~]`, `[sample-looper-box~]`: records and plays back audio loops

with adjustable start, stop, playback speed and pitch, can be synchronized with

other instances of itself and `[note-vel-looper]` instances.

## Sound synthesis (synth)

`[pulsewidth~]`: rectangle oscillator with pulsewidth modulation.

`[triangle~]`: Triangle wave oscillator.
