Each model in the Aira Compact series shares a similar design, using sounds recreated from Roland's past
synthesisers and
drum machines digitally using their Analog Circuit Behaviour (ACB) technology. They are all portable and have a built-in
lithium-ion battery, similar to the design of Korg's
Volca series. and USB-C connectors to interface with other devices. At the top right of each model, there is a volume control.
Models T-8 Beat Machine The T-8 is a drum machine loosely based on Roland's
TR-808,
TR-909, and
TR-606. It has six drum sounds available: bass drum, snare drum,
clap,
tom, open hi-hat and closed hi-hat. Each sound has control over its tuning (with the exception of the hi-hats) and
decay envelope.
J-6 Chord Synthesizer The J-6 is a synthesiser using sounds based on Roland's
Juno 60. The sound engine consists of 64 presets and allows control over the filter cutoff,
filter resonance, envelope attack and envelope release. It has oscillator (with
square,
saw and
noise waveforms, in addition to sub oscillators),
LFO, filter (which will not
self-oscillate) and envelope sections, as well as
chorus, delay and reverb effects. As well as the basic waveforms, users can "draw" their own or use the "Osc Chop" function to make more metallic sounds. Unlike the monophonic original, it is four-voice polyphonic. The S-1 has a 64-step sequencer with motion recording and can save up to 64 sequences. == Reception ==
