Specific notes on my audio workflow.

General

  • MIDI hardware
    • Yamaha DJX
    • Korg Nanokontrol 2
    • Numark DJ2GO


  • Session management
    • Cadence
    • Non Session Manager
    • JACKPatch - NSM util to save jack patching
    • http://i3wm.org/docs/layout-saving.html - create layout, save to JSON, edit configs to uncomment/edit window title/class, restore from JSON


  • Audio systems, routing and hosts
    • ALSA
    • JACK - jackd 2, multiprocess, gui config via dbus. to try jackd 1 for speed later.
    • alsa_in/alsa_out - for adding additional input and output devices to jack
    • Patchage - JACK/ALSA patchbay
    • Carla - plugin host (LV2, LASDSPA, DSSI, Linux/Windows VST). MIDI automation CC per parameter.
    • Ingen - plugin host (LV2) and patcher. MIDI learn.


  • MIDI routing
    • a2jmidid - via Cadence, as jackd 2 doesn't do the Metadata API yet
    • mididings - filtering, scripting, switching via 'scene' changes
    • jack_midi_dump - another monitor, basic and quick to stdout


  • MIDI sequencing
    • sequencer64 - no MIDI record control (in dev) or MIDI learn
    • harmonySEQ - no recording. sequences and LFOs with multiple patterns, MIDI learn for: sequence toggle/one-shot, note/chord/octave change, pattern change, tempo and sequence sync
    • CCStepper - no recording. Windows VST.


  • MIDI parts
    • Kick
    • Snare
    • Hi-hat
    • Other percussion
    • Bass
    • Phrase A
    • Phrase B
    • Phrase C
sequencer64 pattern GUI layout:
Kick 1 Snare 1 Hi-hat 1 Perc. 1 Bass 1 Phrase A 1 Phrase B 1 Phrase C 1
Kick 2 Snare 2 Hi-hat 2 Perc. 2 Bass 2 Phrase A 2 Phrase B 2 Phrase C 2
Kick FX 1 Snare FX 1 Hi-hat FX 1 Perc. FX 1 Bass FX 1 Phrase A FX 1 Phrase B FX 1 Phrase C FX 1
Kick FX 2 Snare FX 2 Hi-hat FX 2 Perc. FX 2 Bass FX 2 Phrase A FX 2 Phrase B FX 2 Phrase C FX 2

to redo:

  • sequencer64 - MIDI control config - keyboard mapping - see Audio#sequencer64
    • start -
    • stop - nano stop - cc42
    • pause (stop/start toggle) - nano play - cc41
    • screen-set up - nano marker > - cc 62
    • screen-set down - nano marker < - cc 61
    • screen-set play - nano marker set - cc 60
    • bpm down - nano cc61 127
    • bpm up - nano cc62 127
    • mod thru toggle/on/off
    • mod record
    • mod queue - b4
    • mod solo toggle/on/off
    • mod replace - c5
    • mod snapshot - c#5
    • mod group learn - d5
    • mod group mute select - d#5
    • pattern toggle - 0-31 in sequencer64 - c2 (32)-g4
    • toggle between sequencer64 controls and playing notes/chords - e5?
    • mididings scene mod between toggle and on and off?


[OPR INV STAT D1 D2min D2max] (toggle / enable / disable), where;

  • OPR=on/off
  • INV=inverse
  • STAT=MIDI status byte(channel ignored)
  • D1=data1
  • D2min=data2 min
  • D2max=data2 max

Session setup commands

cadence
  # gui, optional, easiest. input device can be entered manually if not autodetected.

# cadence-session-start -s
  # cadence script to start jackd, divert from pulseaudio, etc. might work for you.
    # if fails, try cadence-session-start --reset

non-session-manager -- --session-root path_to/NSM_projects_root
  # i.e. non-session-manager -- --session-root ~/audio/NSM
  # same session root for all projects

NSM entries: 

JACKPatch
  # nsm specific util to save and restore jack connections

nsm-proxy a2jmidid -eu
  # because cadence never managed to autostart this and misses -u arg anyway

nsm-proxy patchage -A
  # connection manager gui. ctrl-g, ctrl-f to sort connections
  # via nsm-proxy for the -A argument to not load ALSA

carla
  # plugin host

nsm-proxy python path/to/mididingsscript.py
  # MIDI routing

nsm-proxy xterm -e jack_midi_dump
  # MIDI monitoring

nsm-proxy nsm-sequencer64
  # via nsm-proxy, requires an empty midi file


( optional
 nsm-proxy nsm-ingen
   # via nsm-proxy, hack of sequencer64 script above, copies in a blank project, starts ingen modular host engine and gui
   # ingen -eg project.ingen
)

( optional
 nsm-proxy alsa_out -j "USB Out 1" -d hw:5 -q 1 2>&1 1> /dev/null &
 nsm-proxy alsa_out -j "USB Out 2" -d hw:6 -q 1 2>&1 1> /dev/null &
   # additional 2 stereo outputs, USB soundcards for DJ main and headphone
)

Cannae

  • Cannot yet do/use
    • MIDI controlled MIDI looping - no software good enough yet, would allow live loop of mute and effect changes
      • sequencer64 - no MIDI start/stop/arm.
      • Giada - audio/midi looping - problems between nanoKONTROL2s no button off note off CC and parameter scales. fiddly midi control; learn but no 'mod' like sequencer64, i.e., no MIDI 'channel' (sample/sequence) select or channel groups - every item requires unique MIDI CCs and learns for each of it's functions.
    • External interactive tempo changes
      • klick doesn't do JACK transport and OSC mode (from gtklick) at same time
      • Jack Director only has set bpm presets triggerable by midi
      • InConcert doesn't take external input or display bpm, crashes often
    • Samples
      • petri-foo - broken, always starts from 0 :(
