Specific notes on my audio workflow.

Hardware

  • MIDI hardware
    • Yamaha DJX
    • Korg Nanokontrol 2
    • Numark DJ2GO
    • MIDI to USB adapter for DJX

Software

  • Session management
    • Cadence
    • Non Session Manager
    • JACKPatch - NSM tool to save JACK patch connections
    • i3 - dynamic tiling window manager with i3 layout saving features, automatic session save with i3session


  • 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 to JACK additional input and output devices beyond the primary sound device.
    • 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 'scenes' and MIDI program change messages. m_mididings.py
    • jack_midi_dump - MIDI monitor, prints to terminal stdout.
    • midifilter.lv2: ScaleCC - scale CC range sent to delay down for easier time sync length selection
    • midifilter.lv2: MIDI Note to CC - note to CC
    • midifilter.lv2: MIDI Duplicate Blocker - for live vs. seq64 notes
    • Piz: midiProgramChange - from the above to mididings for scene changes
    • Piz: midiCCToggle - momentary to toggle
  • MIDI sequencing
    • sequencer64 - no MIDI record control (in dev) or MIDI learn. use wip branch where these are/will be implemented.
    • 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 - 64 steps max, no recording. Windows VST.

Session

To do

  • update this page
    • currently I'm testing DAWs for easier signal routing, Ardour seems to be winning so far
  • mapping computer keyboard to MIDI keyboard for more than just seq64 use - midikb
  • MIDI controlled MIDI routing/switching using mididings scenes
    • find a better workflow
    • use cc toggle more? (overtone nanokontrol 2 config?)
    • need "if note held, this, else"?
    • scenes for
      • nano control of seq64 horizontal column level selection?
      • delay sends - function key select scene, nano buttons to send, nano rotary for feedback? nano cycle to toggle momentary or toggled send
      • gate/lfo sends - function key select scene, nano buttons to send, nano rotary for level, nano cycle to toggle momentary or toggled send
      • drum midi receive select, allows one/some/all.
        • mididings outputs for ersdrums, drum kit sf, drmr - scenes: ersdrums, kit, drmr, ersdrums+drmr, ersdrums+kit, ersdrums+kit+drmr
    • harmonic control
      • set the key - kick/bass/synth
      • play various kinds of chord progressions - synth
  • part/pattern progression switching - seq64 vertical columns and sets, with mute groups
    • part/channel preset switching - set play? move up/down in column feature request? manual.
  • pick an fx plugin rack
    • delay - cc range filter/alter for fine synced delay time control - tal dub
    • pick reverb plugin - use/make nice presets - mverb?
    • pick gate -
    • pick eq - dj hi/low pass? - dj2go three faders for low mid hi
    • pick filter -
    • pick autopanner -
    • pick fuck shit up - anarchy rhythms?
    • pick a metronome -
    • audio level fade change cc buffer?
  • sequence64 CC patterns - bottom 2 rows of a column/set 2 columns

Setup commands

cadence
  # start jack with

#todo - non-gui start
# cadence-pulse2jack
# pacmd set-default-source jack_in && pacmd set-default-sink jack_out

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
  # i alias the command "nsm" for this, starting in a terminal for output/error messages

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 mididings -f path/to/m_control.py [1]
  # MIDI routing

nsm-proxy livedings -l 56801 -p 56800 -T -f "Sans 22 bold" -F "Sans 22 bold" -w 50 -n "control"

nsm-proxy mididings -f path/to/m_drums.py [2]
  # drum selection. to redo.

nsm-proxy livedings -T -f "Sans 22 bold" -F "Sans 22 bold"

nsm-proxy xterm -e jack_midi_dump
  # MIDI monitoring

nsm-proxy nsm-sequencer64
  # via nsm-proxy, requires an empty midi file
  # make sure set to jack transport master

radium_compressor

( 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

Bugs

(and nitpicks)

  • Cannot yet do/use/is annoying
    • Session management
      • NSM - undeveloped UI, can't delete/move/rename sessions, no delete confirmation, new session/client button confusion, nsm-proxy doesn't save label first time. no jackpatch connection state file save/argument, loses states on bad crash. mostly does its job though..
      • i3 - working towards a sound layout save and restore process..
      • Carla - plugin state has to be manually loaded, plugin windows need to be manually opened (nsm?) [4]
      • Carla - takes a while to close [5]
      • Carla - no NSM portability yet [6]
    • Routing
      • jack2 - lacks Metadata API so no pretty device port names [7]
      • Patchage - doesn't auto-refresh when a client changes in/out ports
      • Patchage - has Sprung Layout and Sort Ports By Name on by default, no start flag [8]
      • Carla - crashes after a plugin is renamed [9]
      • Carla - has a max plugin instantiation limit of 10s, ErsDrums loads only 50% of the time depending on load
      • Carla - cannot reorder/group plugins in rack [10]
    • DAW
      • LMMS - no LinuxVST or LV2 [11]
      • Qtractor - doesn't see some VSTs linked by Airwave..
      • Qtractor - plugin MIDI ports are exposed through jack "system" block?! name is unuseful "midi_playback_13"
      • Qtractor - clicking on a bus option bus not changing it, then clicking another bus prompts to save (no) change
      • Qtractor - ERSDrums - on a MIDI track and no audio outs, on a Audio track and no MIDI ins?
      • Ardour - can't undo various tasks
      • Ardour - "Add New Subgroup Buss" doesn't work
      • Ardour - can't create busses in routing page
      • Ardour - plugin output channel numbering reversed/whack! (ERSDrums at least)?
      • Ardour - no virtual piano to plugin MIDI input for testing
    • MIDI controlled MIDI looping - no software good enough yet, would allow live loop of mute and effect changes
      • sequencer64 - no MIDI start/stop/arm just yet [12]. can't change BPM whilst running yet [13].
      • Giada - audio/midi looping - problems between nanoKONTROL2s no button off note off CC and parameter scales [14]. 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 [15]
      • Jack Director only has set bpm presets triggerable by midi
      • InConcert doesn't take external input or display bpm, crashes often
    • Synthesis
      • ZynAddSubFX / Yoshimi - no host tempo sync for lfo/etc. [16]
    • Samples
      • petri-foo - broken, always starts from 0 :(
      • Specimin - no mp3 at least until the end of 2017 due to patents
