Sequencer 16 tracks, 32,000 notes, port SmartMedia, PC to store the midi file or all the contents of the beast, over 500 sounds, with a nice screen handy.
1 audio in (microphone or guitar), 1 audio out, midi IO, although a full multieffect + reverb + chorus.
it is small, easily transportable.

UTILIZATION

The QY100 is very intuitive, the manual very complete and clear.
The sequencer is very rich, it records everything (the pedal of a digital piano, the resonance of an envelope), for against all these parameters do not directly accessible sounds (no knob).
edit for all, it is very pleasant with its "big screen".

SOUNDS

The problem is the sound (4Mb ROM). It is far from roland sounds or synth ...
despite all the modifiable parameters and the effects it sounds always QY (too crooked).
However, it is sufficient to deal

OVERALL OPINION

I use it for 2 years to compose, traveling is very small and perfect because it offers the possibilities to compose a piece of insane 16 tracks.
I also used to record the tracks in midi digital piano fits perfectly with the song composé.je some notes and editing, the QY driving the piano, I record the correct sound of the piano.
only drawback to this machine, sons.ils are very inadequate.
was my first sequencer, the value for money is good.
