Trs many tones available on almost two octaves. Tunable. Bumblebees and sing on two midi channels. Sensitive with 1 or 1 / 2 your best (ncessite of stopping and restarting).
Audio Out / Headphone Out + MIDI.
Practical use audio to train without interfering with the neighbors. The sound is unsuitable for anything other than the solo practice with headphones, since the dynamic range too much for each note (no possible use in groups)
By using MIDI, used to control a chantilloneur as VSampler 3. The above default deficits disappear. (That's why I rpertori in "MIDI controllers." Flagship is its function.)
Because they are sensitive keys, it dlicat with hands sche ... or too wet! This technology also ammne noise in the audio, even in the MIDI (weight problem).
Finally, the use of li always sensitive keys 0 / 1, no glissendo CONTRL or fake finger possible.
BUT at what these del default quality is an excellent price for any person in an apartment, and / or who wants to control MIDI instruments.
