Audio and routing

Item	Specification
Audio inputs	2 independent inputs for stereo or dual-mono operation
Audio connectors	6.35 mm (1/4-inch) TS, unbalanced; each loop channel has separate send and return sockets
Input routing	Either input can feed either bus; one input can also feed both buses
Signal paths	2 analogue buses: Bus A and Bus B
Reorderable loops	5 mono loops (L1–L5), with relay-switched true bypass
Loop assignment	L1–L3 assignable to Bus A or Bus B; L4–L5 on Bus A only
Fixed stereo loop	L6/L7 form the left/right channels of the final stereo loop, with relay-switched true bypass
Audio outputs	2 outputs for stereo or dual-mono operation
Mixer	2-channel analogue mixer for blending Bus A and Bus B
Input buffers	Switchable buffers with a shared bypass control
Output pads	Selectable nominal −6 dB pads on both bus outputs, before the mixer
Polarity control	Selectable polarity inversion on Bus B
Virtual blocks	2 mono DSP blocks (V1 and V2), each independently bypassable or assignable to a Pre, Mid or Post position on either bus

Virtual block positions

Position	Bus A	Bus B
Pre	Before slot 1	Before slot 1
Mid	After slot 2, before slot 3	After slot 1, before slot 2
Post	After slot 5	After slot 3

Slots are positions in the reordered chain, not fixed loop numbers. Bypassed loops still occupy their slots. Both Post positions are before the output bus swap and final stereo loop.

V1 and V2 can use the same position or different positions on either bus. When both use the same position, the signal passes through V1 followed by V2. Bypassing a virtual block keeps the signal on its analogue through-path.

Digital audio and switching performance

Item	Specification
Sample rate	48 kHz
Digital audio word length	32-bit
Virtual-block latency	Digital processing adds latency; account for it when mixing parallel paths.
Preset switching	Transition time depends on the routing, effects and models being recalled. Test your performance presets together.

Round-trip latency describes audio passing through a virtual block. Preset switching time describes the transition between presets and is a separate measurement.

MIDI implementation

PC and CC numbers below use 0–127. Channel messages use the receive channel selected in Preferences (1–16). Clock is a MIDI system message and does not use a channel. Enable Receive or Thru for mapped input control.

Program Change messages

PC number	Action
0	Toggle tuner.
1–5	Select Jam preset slot 1–5.
6–10	Simulate pressing footswitch 1–5.
11–15	Simulate releasing footswitch 1–5. Pair each with its corresponding press.
123	Open the Jam Page.
124	Open the active preset in the Preset Editor.
125	Open the Home/settings carousel.
126	Open the mixer.
127	Save on the current page, where supported.

Control Change messages

CC number	Value	Action
0	0–127	Drive the EXP BT expression source. It affects parameters assigned to that source; it is not a general “currently selected knob” command.
1–60	0–127	Recall a library preset using the live map: up to 7,680 addresses.
61–121	0–127	Recall a song using the live map: up to 7,808 addresses.
122	0–127	Recall a setlist using the live map: up to 128 addresses.
123	0	Toggle recorder.
123	1–5	Remove the preset assignment from Jam slot 1–5. Save the song if you intend to keep the change.
123	6–10	Put the active preset into Jam slot 1–5. Save the song to keep it.
124	0	Toggle global loop bypass in the editor.
124	1–7	Toggle physical loop L1–L7 bypass in the editor.
124	8 / 9	Toggle Virtual 1 / Virtual 2 bypass in the editor.
124	11 / 12	Toggle Virtual 1 amp NAM / IR bypass.
124	14 / 15	Toggle Virtual 2 amp NAM / IR bypass.
127	0	Request Bluetooth MIDI map synchronisation.
127	126 / 127	Bluetooth MIDI heartbeat / acknowledgement; reserved for the connection protocol.

Editor commands require the relevant editor to be open. Unlisted values have no documented performance action. Library address capacity is not a promise about storage space; available space depends on your files.

The live map is the authority for each saved item's address. Outgoing preset and utility messages support PC and CC with a destination channel, number and, for CC, value. See Clock, synchronisation and MIDI thru for clock and forwarding setup.

Compatibility

Connection or file	Requirement
Audio	Unbalanced TS connections. Use the labelled send and return for each loop channel.
Expression	TRS expression connection, calibrated in Expression / Control. Ask support about model-specific wiring and electrical compatibility.
CTRL	Isolated TS relay contacts for compatible amplifier/footswitch switching inputs. Ask support about the amplifier's switching requirements if uncertain.
USB	A computer USB host and a data-capable cable; Artemis remains powered by its DC supply. Use the Launchpad transfer guides.
MIDI	Standard 5-pin DIN connections for the wired procedures in this manual, with matching channels and message numbers.
NAM	Valid .nam captures. Model complexity affects processing demand.
IR	Impulse responses in .wav, .wave, .aif, .aiff or .flac format.

The pedals shown in the walkthrough illustrate loop setup. Their inclusion is not a compatibility list for unrelated expression or amplifier-control connections. Contact support with the exact device model when checking those connections.

Glossary

Term	Meaning
Loop	A send/return connection that inserts an external effect into the signal path.
Send / return	The send feeds the effect's input; the return receives its output.
Bus	One of Artemis's two signal paths, Bus A or Bus B.
Slot	A position in an effects chain or song layout. Its meaning depends on the page; a preset slot position is not a rear-panel loop number.
Virtual block / virtual loop	One of the two digital processing chains that can be placed within a bus.
Preset	A saved sound containing routing, effect and associated control settings.
Song	A five-slot performance layout containing presets or utility actions.
Setlist	Songs arranged in performance order.
Bypass	Skip an effect or processing block while allowing the signal to continue.
Dry / wet	Dry is the unprocessed signal; wet is the processed signal.
Polarity	The positive/negative orientation of a signal. Reversing one path's polarity changes how it combines with another path.
NAM	Neural Amp Modeler; a captured model of an amplifier or pedal loaded into a virtual chain.
IR	Impulse response; a file used to reproduce a linear response, such as a cabinet and microphone response.
MIDI PC / CC	Program Change and Control Change messages used to recall sounds or control functions.
TS / TRS	Tip-sleeve and tip-ring-sleeve jack connections. Artemis's audio connections use TS; expression inputs use TRS.
