Audio setup old

Specific notes on my workflow. General notes on Audio.

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

• Desire
  • MIDI controlled MIDI looping - no software good enough yet.
  • MIDI effect send and control
  • MIDI controlled MIDI routing/switching
  • Part selection and control? 'mod' key for function
  • Easy BPM alteration from a Jack master. Decimal numbers for fine control?

• Parts
  • Kick
  • Snare
  • Hi-hat
  • Other percussion
  • Bass
  • Phrase 1
  • Phrase 2
  • Phrase 3

• Keyboard control sections
  • pattern toggle - 0-31 in sequencer64 - c1-f#2
  • screen-set up
  • screen-set down
  • screen-set play
  • mod queue
  • mod replace
  • mod snapshot
  • mod group learn
  • mod group mute select
  • bpm down
  • bpm up
  • toggle between sequencer64 controls and playing notes/chords

• midi want
  • part progression switching
  • part/channel preset switching
  • LFO frequency fraction selection for effects

• Session management
  • Cadence
  • Non Session Manager
  • JACKPatch - NSM util to save 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 software
  • ALSA/JACK
  • Patchage
  • Ingen - lv2 host and patcher
  • Non Mixer

• MIDI software
  • a2jmidid - via Cadence, as jackd 2 doesn't do the Metadata API yet
  • mididings - filtering, scripting, switching via 'scene' changes
  • GMIDImonitor - displays traditional MIDI CC names
  • sequencer64 - no MIDI record control or MIDI learn yet
  • harmonySEQ - no MIDI record. sequences and LFOs with multiple patterns, MIDI learn, some event scripting

• Software not used
  • 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.

Session setup commands:

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

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

non-session-manager -- --session-root path_to/NSM_projects_root
  # same session root for all projects

NSM entries

jackpatch
  # nsm specific util to save and restore jack connections

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

non-mixer
  # modular mixer, osc/cv controllable

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

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

jack_midi_clock
  # transforms JACK transport tempo beats to MIDI ~Clock pulses
