So basically, I need the SparkLE controller to get the polyphony and the 64 step sequencer? Are there going to be BeatStep firmware updates and MIDI implementation charts to address these issues? The BeatStep does have it pluses: it can work as a standalone (no computer required) and has CV/Gate output should I encounter modules that use them. I am trying the demo version of the Spark2, and love the vintage drum sounds.
Still, the layout of the Spark2 program is similar to the BeatStep's 2x8 pad layout.
