I might ask, what is it about the BK7-m that you need improving?

For its price point (well under a grand US used) it’s an extremely good unit. It’s also a killer drum machine if that’s all you need.

The FC-7 footswitch input makes it a breeze to use live kicking fills and variation changes... in fact, that’s one of the things that works against the Ketron, IMO. The whole idea of a module rather than a keyboard version is the admission that you are playing something else. It’s very hard to place a module somewhere that all the myriad functions you need to use live (fills, variation, breaks, ending buttons etc.) are as easy to get to when either playing another keyboard, or even a different instrument like a guitar or accordion, etc..

That’s why all the main arranger buttons are right by the keyboard on an arranger... you need to quickly trigger them and get back to playing as fast as possible. But with both hands playing a guitar, or accordion, or another keyboard, you can’t get them that close, hence the need for a multi-button footswitch. Now you can probably buy an expensive MIDI foot controller for the Ketron, but doing the job with a simple switch unit allows hooks into things on the OS that may not have MIDI codes to trigger.

Me, I’d give my hind teeth for a module version of the BK-9, but let’s be real... the keyboard version cost $2400 at launch, so a module would be unlikely to be much less! I love my BK7-m, I use it as a sound module for my keytar, and as an emergency backup to my main rig. Bang for the buck... amazing!
