The =E2=80=9Cremote=E2=80=9D box was my first thought, too, but how to = get a cable through the original case would be the challenge in my = opinion. The panel board must connect to the main board with a ribbon = cable or some other standard connector, so a cable could be made to = adapt the original connection to a custom one. Some kind of circular, = multi-pin connector would be ideal, but I never like drilling extra = holes, not even on the back panel. Maybe the cassette interface jacks are not needed? I assume the SC40 has = SysEx support that totally replaces cassette storage. An alternative would be to manufacture a new MIDI board, but leave out = the MIDI thru jack and replace it with a different circular, multi-pin = connector. That would be totally reversible. On the topic of re-engineering costs, all it really takes is for one = person to love their Pearl SC40 enough to pay several hundred dollars = for the up-front design work. Then the PCB Gerbers could be shared with = the community so that additional ones could be made without new = engineering work. Once all the measurements are made and confirmed, = making duplicates is a lot less expensive. It could even be a kit, = although kits have annoying overhead for the central person. The problem with estimating demand is that a lot of potential exists, = but when it comes down to actually forking over the money the market = suddenly shrinks. That unpredictable market shrink raises the effective = per-unit price, and then more people drop out when they learn that the = actual price is higher than predicted. It=E2=80=99s far easier when = someone with deep pockets just takes that big first step. Subsequent = steps are cheaper and more predictable. Ideally, if a little profit is = made on the duplicates, then the original buyer can be slowly reimbursed = for their huge leap, dropping their cost. The thing is, there are so many old synths where modern updates = =E2=80=9Cshould=E2=80=9D enjoy some amount of demand. In one sense, = custom upgrades or retrofits are =E2=80=9Ceasy,=E2=80=9D it=E2=80=99s = just predicting which ones will actually succeed, and at what price = point they wouldn=E2=80=99t represent a loss for the maker. I still have = a Prophet 5 Rev 2 upgrade board design on the back-burner. In that case, = I=E2=80=99m the sucker willing to pay for the first one, hoping that = more people will want a copy. But it seems that I=E2=80=99ll never = finish that project... Oh, the first-world problems!
