OB Dave determined the special resistance track several years ago... https://forums.musicplayer.com/ubbthreads.php/topics/2887601/re-expression-pedal-summary#Post2887601 I'm sure Alps has no problem accommodating Yamaha's needs.

Note that the RK163 "Product Line" stock units are all indicated as 10k resistance... https://tech.alpsalpine.com/prod/e/pdf/potentiometer/rotarypotentiometers/rk16/rk16.pdf Perhaps Alps can offer some insight into the RK1631110G specifics... https://tech.alpsalpine.com/inquiry/catalog?lang=en

Alps RK16 pots can be configured in various ways... https://tech.alpsalpine.com/prod/e/pdf/potentiometer/metalshaft/rk16/rk16_varietyother.pdf By "custom", I mean a variation that is not normally stocked/off-the-shelf. For the RK1631110G, I don't know specifically what the G suffix indicates.

I suspect the "Yamaha site" you mentioned is yamaha24x7.com This is the pot info... WF876300 VR ROTARY B 50.0K RK1631110G FC-7 WF876300 is the Yamaha part number RK1631110G is likely the Alps number, which may be a custom device

If the MOX8 is available, it has a built-in USB audio interface. Here's how to use it... http://www.motifator.com/index.php/support/view/mox6_mox8_basic_audio_recording If the Yamaha Steinberg USB Driver for Windows 10 isn't already installed on your computer, it can be downloaded here: https://usa.yamaha.com/support/updates/index.html?c=music_production&k=MOX

Agreed. All the keybeds I've ever seen with diodes on them have used signal diodes 1n914 or 1n8148 (same size diodes, little bit different specs). If you can desolder and solder, DIY and save. I suspect you probably meant to refer to a 1N4148. The 1N8148 is a TVS (Transient Voltage Suppression) diode, not appropriate for the purpose and about 100 times as expensive as a 1N4148.

Sorry, although my previous post immediately followed yours, it wasn't meant to question what you posted - I only mentioned Universal SysEx at all since you brought up the topic. I was mostly addressing previous comments in the thread which seemed to indicate a small misunderstanding concerning MIDI channels, and I wanted to clarify the issue.

There seems to be some confusion over MIDI Channel versus Device ID. SysEx messages don't include MIDI Channel. The first three bytes of a typical SysEx message might be... F0 43 10 where... F0 = Start of Exclusive 43 = Manufacturer ID (43 is Yamaha) 1n = Device Number, n = 0~F (1~16 decimal) followed by model ID bytes, then data, and finally... F7 = End of Exclusive Device Number isn't MIDI channel, it's an identifier for which of the up to 16 synths of the same model you want to direct the message. I suspect that few of us have multiple "whatevers" in our rigs, so this capability doesn't usually get much use. It may have had more application when synths tended to be mono-timbral, and a bank of them was needed to get multiple sounds simultaneously. By the way, that third byte isn't always "1n" - for Yamaha, that would signify a Parameter/Mode Change message, while "0n" is for Bulk Dump, "2n" for "Dump Request", and "3n" for Parameter Request messages. Universal SysEx, somewhat of an oxymoron, doesn't have Manufacturer ID.

Since the CT-X5000 is USB-MIDI class compliant, see this for some choices: https://www.casiomusicforums.com/index.php?/topic/15884-computerless-usb-midi-solutions-for-the-modern-casio-user-connecting-usb-midi-devices-without-a-computer/

Thanks for the update, and it's great to see that the repair was successful! Thanks also for well-wishes - I'm OK, just otherwise busy and my dial-up internet connection limits my ability to participate in this forum.

User Voice data, Performances, Patterns, Songs, Utility mode (System) settings are all stored in flash memory in your Motif ES. It seems it's been working for 17 years.

Try this: http://web.archive.org/web/20070210163316/http://www.yamahasynth.com/products/tg/index.html They're in .MID format.

If you have the Yamaha part number(s), https://www.yamaha24x7.com/ Otherwise, https://usa.yamaha.com/support/parts_manuals/index.html

It remains to be seen what additional sounds Yamaha will provide. It wouldn't surprise me if user requests might influence that. However, the PDF from Easy Sounds says: "CP is Yamaha's acronym for Combo Piano." ---- and ---- "The new CP series from Yamaha provides an answer to the question of what standards are set for a Stage Piano today." Those statements may or may not be a clue to Yamaha's intent.

Claim is that sounds will be expanded with frequent OS updates. http://www.easysounds.eu/MusicProductionGuide_2019_01_EN.pdf
