See the data sheet. No velocity sensitivity. No push buttons on the pedal. No MIDI. Polyphony "unlimited".
I regret that there is no "break" on the drum rhythms and only 8, but hey it was the standard at the time.
I do not have the manual but it's very easy to use. Can be stacked full of sounds (all SEUF the "special presets" which had their own sound).
The keyboards are very nice to play, but not silent even with a headphone is just annoying lady who watches TV.
I think the buttons could have been better prepared pourqu'on can more easily access the most useful things during the game, but good.
It is a large organ analog era, it does that is suitable style "organ variety" and the old songs. The amplification is not very powerful but good enough and strong enough to play at home.
I like the chorus, it can enable / disable or do slow / fast (effectively "leslie") easily with the buttons right below the keyboard. But it tends to produce a lower volume so it rotted a little balance in the score.
There is a low pass filter fixed frequency on the lower keyboard, so that the sounds of gently accompanying lower keyboard, but it cuts both ways because if you want to play a second voice down, you hear little. The detector arrangement the drum machine is not very smart, he likes to spills and not too low for third straight is impossible.
The "good" is the standard of the time, of course. Do not try to compare the sound of "violin" of this organ with that of a current rompleur!
I've had two weeks and spent plenty of time on it. It's a shame that instruments "has been" like that go in the trash every day. It really explodes on! Having a pedal releases the left hand, and analog warmth of it warms you to the core!
Too bad y'ai no MIDI, but otherwise it is fun to play. We sit and we play, not as a workstation where you spend two hours in sequence before a little fun. As well as the object is beautiful!
Try playing one or two tubes or Mike Brant Charles Trenet it and you will not want to let go!
