Flavie,
A few responses for you ...
1- Basic sequencer like the one that Roland G1000 has.
>>>AJ: This is available on the Ketron X4 module (under EFFECTS - F2).
2 - General EQ, like the one that Yam 9000Pro has.
>>>AJ: This is also available on the Ketron X4 module. The XD3 module has a bass boost feature found under Play Control 2/2. You can select what frequency you want to boost and buy how much.
3 - Compressor and three band EQ for the mics.
>>>AJ: This is a good idea for future products. We will definately take this into consideration.
Thanks,
AJ
