Ketron has had full sequencers in the following modules.

Ketron X1
Ketron X1 Oriental
Ketron SD1
Ketron SD1Plus

In the X-series, you have the option to double the sequencer memory from 150,000 to 300,000 notes.

In the SD1 series, it was fixed at 150,000 notes.

In AUDYA (currently) you can record your performance and save as a MIDIfile, Wave file or MP3 (vocals can be saved on the last 2 formats).

Thanks,

AJ
