Groovyband manages 16 parts (8 automatic accompaniment parts, and 8 parts you can play by yourself). Each of these parts is like a mixer bus to which you can add insert effects to shape the sound of the playing instruments.
The number of insert effects you can use all at once (and how many in series on a given part) is limited by two factors: what is available in the hardware (PSR, Tyros, Genos) and what Groovyband allows you to exploit of the hardware capabilities (depending on the edition: standard, pro, platinum).
The following table shows the possible combinations (parts x inserts):
|Arranger Model||HW DSP #||Standard||Pro||Platinum|
|PSR SX 700||5||4×1||5×1||5×1|
|PSR SX 900||8||4×1||8×1 or 4×2||8×1 or 4×2|
|Genos||16+||4×1||8×1 or 4×2||16×1 or 8×2|
In addition to the “regular” insert DSPs shown in the table, on all models there is an additional “variation” DSP that can be routed as a global send bus, or as an additional insert (on top of what listed in the table, for each program edition).
Your purchase decision should also be guided by the number of styles available (which is different in each edition). All the styles available in the Platinum version will sound great even on PSR models. In fact the DEMO edition (which has all the styles available in the Platinum edition) is limited to 4 insert DSPs by conscious choice. If you like what you hear (and we are sure you will!), things can only get better with the more capable software editions or hardware.
