I fully agree with the post by "to the genesys"

His comments are almost identical to what I have said when, some time ago, I made a post on here and also on another site regarding the lack of modules.

I have, in the past, already written to Roland and Korg because both of these companies have previously sold some of their products in module form.

Ketron is alone among the arranger manufacturers in that they have always produced a module. I still use a Solton MS40 - still ultra reliable after many years of use and humping around on gigs. This has a few sounds which are still better than some on both my Tyros3 & Technics KN7000.

The Ketron SD3 is a brilliant module, let down only because it has stuck with the outdated floppy disk rather than build in a USB pen drive fitting. It can be bought with a Hard Drive but this is a rip-off by Ketron - the price difference is disgusting when you consider the cheap prices of giant hard drives which are on the market now.

As I have stated before, If every manufacturer offered a module, I would definitely buy them all - easy to swap around (or even use in unison) and there is no better way of sussing a keyboard out without a big spend. It was the use, many years ago, of a Technics SMAC 1200 module, (which I still have - working perfectly) which turned me onto Technics keyboards and led to me buying many of their products. This should be all the incentive any manufacturer needs.
