zealtv/bop

Fun and friendly modules for Pure Data Vanilla. bop 🐤 is suited to embedded, distributed, and miscellaneous digital musical applications.

bop's Issues

Ability to target modules by type

Module parameters should respond to both
parameter-name $1
as well as
bop.module-name parameter-name $1

This way messages can be differentiated between modules while still being passed through a chain

Add LFO command to params

targetParam sine 1 // hz sine defaulting between 0.25 to 0.75
targetParam sine 5 1 // 5hz sine from 0. to 1.
targetParam sine 0.1 0.2 0.4 // 0.1hz sine from 0.2 to 0.4

additional arguments ignored

Param modes:
Sine

• rate
• rate depth
• rate low high

Random

• smooth
• sh-rate smooth
• sh-rate low high
• sh-rate low high smooth

hyperstave style group x-fade

something like https://github.com/zealtv/elevon but simplified or generalised.
attenuates and disables a subpatch according to one or more inputs and a function.

• bop.ringmix~
• bop.hyperstave~
• bop.function~
• bop.mathmix~ // takes a function

Application as:

• a circular panner
• spatial mixing
• virtual spatial objects

Friendly with the clone object and multichannel cables.

bop.sampler~ requires refactoring

bop.sampler~ attack and release

fade-in and fade-out should be attack and release.
when not in loop mode, release should trigger a fade that is the minimum of the (fade-out-timesampleDuration) and 1-currentPositionsampleDuration.
This would act as a release, and automatically shorten the release time to meet the end of the sample.

bop.instrument~ errors on loading

Not an issue when creating the module, but when loading previous state these errors are thrown:
$2: argument number out of range
bad arguments for message 'label' to object 'cnv'

likely due to loadbang timing. module still works fine. Low priority.

bop.p.intermal holding onto higher voices

when an intermal with fewer voices than the previous intermal is entered, the higher voices hang. Need to count voices and flush unused ones.

bop.p.blineseq ignoring durations of 0

This argument works...
delay-level 0.1 0.01 0.1 2000 0.5 3000;

This does not ( delay level slowly approaches 0.1 initially)
delay-level 0.1 0.01 0.1 2000 0.5 3000;

Create bop.sampler

Create bop.out module

Add MIDI, Velocity, Channel format for unison capable modules

bop.intermal, and later modules (frets) are capable of outputting unison voices.
Consider implementing a 3 element list to include voice id.

modules can differentiate between 2 and 3 element midi messages, employing poly where necessary.

bop.scope~ displaying 1 as -1 in array view

Rename bop.intermal to bop.semisteps

bop.seq should send messages upstream of itself

this would allow for setting tempo from bop.seq itself. As well opening up other recursive sequencing options

Rename adsr params

use plain language:
attack
decay
sustain
release

note notation converter to compliment musical time notation

|e4
|e#4
|a0
|b1

|e1 127
becomes:
40 127

pipe is best best prefix?

Maybe just as a utility....?

bline~ streaming out floats on held value

consider adding a change and a bang for unchanging values

bop.semisteps should have a hold toggle to work with pluck and strum

notes are flushed when toggled off or new semistep or fret is set.

tempo control and bar multiplication and subdivision notation

1b = 1 bar
2b = 2 bars
b2 = 1/2 bar
b4 = 1/4 bar

bop.strum should work on incoming MIDI

A store of currently held MIDI notes should be kept and noteslider should sweep across them.
A MIDI toggle button could activate this. This would work great with bop.intermal

Create bop.fret module

Similar to bop.intermal but using a strings and frets model:

root 42 //set pitch of lowest string
tune 0.555 //four strings tuned in fourths
fret 0.220 // Em chord

Requires unison MIDI implementation to handle unison voices #12 (comment)

Implement band-limited oscillators

bop.p.number defaulting to range 0 to -1

Seems to be caused via [r $x-get-$x-raw]

Read seq from file

example sequences in ./seq

Update from disk:
[b] update from file
|
[read seq/example.bopseq(

Should open the door to live coding

implement band-limited waveforms

Add step command to bop.seq

Script headers

Scripts should have a header section that is only run once, above an indicator that acts as the loop point.

eg

parameter 0.5;
level 1;
===;
--- stuff happens;
64 127;
- 1000;

bop.fm~ keytrack button should be an adsr enable/disable button

[X] vca
[X] envelope
[X] adsr

👆 something like this ?

decouple internal subpatches from gui to allow for light patches

clicking bop.p.numbox breaks range

Can be seen in the about-bop.p patch but seems to be a broader issue. May have to do with an interaction with bop.p.enum.

bline and blineseq messages not working with bop.p.toggle

create bop.bitpluck

A bitplucking module should be created to compliment bop.intermal.
Perhaps rename bop.pluck~.

bop.noteslider = bop.strum
bop.bitpluck = bop.pluck

bop.pluck~ becomes bop.hit / strike / keys or something... ?

A simple disk streaming sample playback module would be useful for low-resource scenarios

bop.diskplayer
bop.soundplayer
?
