Page 3: Welcome To Loopa
If you have a soldering iron and mid-level DIY experience, it can be built in a few evenings. An extensive build video tutorial will cover each build step. The LoopA comes in two case variants - a cheaper but sturdy full acrylic variant, and a “pro variant” proudly made by Hallik Engineering. ... -

2. Features ● MIDIbox/FreeRTOS (real-time operating system) STM32F4 microcontroller-based application resulting in minimal MIDI jitter/latency ● Responsive and optimized UI for an easy-to-use workflow with a fast learning curve: it is ideal for recording concepts/ideas in your studio and for live performances on stage ... -

2. Attach your LoopA to your favourite synth (synth MIDI OUT to LoopA MIDI IN1 and LoopA MIDI OUT1 to synth MIDI IN) 3. Attach a USB B cable to power up your LoopA (you could use a mobile USB charger, a USB power bank, or just a USB port from your computer) ... -

17. If you are lost somewhere, push and hold SHIFT and the HELP key to get context sensitive information. 18. Once happy with your jam, don’t forget to save it on the DISK screen. If you turn off your LoopA at any time, your last saved (or loaded) session will be automatically fully recalled. ... -

4.2 Encoder knobs ● SCENE Selects the currently active scene. LoopA has six tracks and six scenes and thus stores 36 MIDI clips in memory. The scenes are enumerated from A to F and the tracks are enumerated from 1 to 6, which can be concatenated to “1A” or similar. ... -
Page 8: Status Leds
4.3 Status LEDs Both SCENE and LIVE encoders are partially encircled by status LEDs, which probably look a bit differently (LED sizes and color scheme) in your LoopA, but are arranged in this orientation: ... -
Page 9: Keys
● The six middle LEDs around the LIVE knob indicate the parameter value of the currently active LIVE mode. The upper and lower different-color LEDs are used to indicate the live mode type (labeled "TRANSPOSE" or "BEATLOOP" on the frontpanel), which can be switched by just pressing the LIVE encoder. ... -
Page 10: The Shift Function
5. The SHIFT Function The SHIFT key provides access to shortcuts and additional screens: ● Hold SHIFT: shows the muted/unmuted state of the current track clips and to what scene they are assigned (see above screenshot). ●... -
Page 11: Menu Usage And Loopa Screens
6. MENU Usage and LoopA Screens LoopA offers a two-finger navigation menu system allowing for quick one-handed navigation utilizing “muscle memory” shortcuts to access often-used screens. Navigate to the “Clip Settings” page by pushing and holding the menu key and pressing ... -
Page 12: Setup Screen
Within the SETUP screen, basic runtime parameters of the LoopA can be modified. Changes are directly saved to the SD card file called “setup.txt”, which can also be edited manually in a text editor. To move an active configuration over to another LoopA, copy this file to the new SD card root. ... -
Page 13: Defining Named User Instruments
MIDI clock back to the LoopA and the receiving input port is configured as the MIDI clock master All settings within the setup.txt file can be edited by opening this file on a plain text editor. Certain sections are not (yet) editable within LoopA itself. The “INSTRUMENT” ... -
Page 14: Midi Router Screen
MIDI packets can also be forwarded to (or sent from) a virtual USB port (when connecting LoopA to Windows 10 or Mac OS via USB. Four independent MIDI USB devices are added and could redirect MIDI traffic around a studio. ... -

(if it is present), and upper-row key #4 initializes a completely new session, deleting all track and note data. LoopA will remember the last session loaded or saved upon restart. Copy the relevant files in the SESSIONS directory on the SD card to backup sessions. ... -
Page 16: Tempo Screen
6.5 TEMPO Screen Controls the current playback speed and configures a MIDI metronome for a recording guide or click track: Press upper-row key #1 to select the current BPM to be modified with the VALUE knob. Tip: push and turn the VALUE knob for accelerated speed adjustments. ... -
Page 17: Mute Screen
The lower six number slots show the current sixteenth-note-equivalent playback positions and clip lengths for all six LoopA tracks. A display of 09:64 would mean that playback is at step (or sixteenth note) 9 of a total clip length of 64 steps (or sixteenth notes). ... -
Page 18: Clip Screen
Available clip lengths are 4, 8, 16, 32, 64, 128 steps. ● Key 2 is currently without function but reserved for the clip type for a later LoopA revision. ● Key 3 (Trn) transposes the whole clip. Tip: when this operation is active, press the ... -
Page 19: Notes Screen
6.8 NOTES Screen The NOTES screen allows adjustment of individual clip notes, e.g. to correct minor recording mistakes, or to adjust timing, length or velocity of sequence notes: Use the lower-left SELECT knob to choose the currently active note. A small dotted cursor is drawn around it. ... -

6.9 LIVEFX Screen Use LiveFX functions to alter clips with effects designed for live performance: These operations are selected with the top row of keys and modified with the VALUE knob : ●... -
Page 21: Track Screen
● Keys 1 and 2 respectively define the MIDI port and MIDI channel LoopA should send MIDI notes to for the current track. Four virtual USB ports are also available that could be mapped to software instruments (e.g. VSTs) on a computer. ... -
Page 22: Live Performance Modes
7.1 Live Transposition Mode In live transposition mode, LoopA will transpose any tracks that have LTr ON (live transposition set to on) in their respective TRACK page. It makes sense to disable live transposition for drum tracks in most cases. Jump through preset transpositions by ... -
