I know this may sound like a dumb question but how to I get the battery voltage displayed on my newly aquired DX7S? I can find plenty of mention of the ‘battery check’ on a DX7 but the keys used on the DX7 do not ’seem’ to appear on the DX7S!

I had recently purchased a 2nd (3rd?)-hand DX7 Mk1 with e! card. Previous seller stated unit was bricked; upon powering up the Numeral LED’s shuffled about and the top row of the lcd char screen showed solid blocks. He said the battery was changed by previous owner. I took it in as a project/parts unit. physically flawless…I tested the battery, 2.7v, well within normal operating spec. I disassembled and checked the solder points for the replaced battery, which seemed good. I removed some flux rosin about the battery’s points. Tested for voltage across several traces, which reported good news. I might try the external battery AAA pack. I don’t know if the thing crashed hard when the e! card was installed, before or after the battery change etc etc; seller wont contact me, he got his c-note. Suggestions? Thanks thanks MT

I would be remiss here if I didn't also recommend a piece of software to record on your computer with. I highly recommend not even bothering to install the feature-limited demo software that comes with the FastTrack, and to check out Reaper instead. It is free-and-uncrippled-until-you-you-decide-to-pay-for-it, and then $60 for a noncommercial license when you do. It supports MIDI sequencing and audio recording (on the same track even!), has really easy and useful built-in effects (especially check out the ReaEQ plugin!) and does a LOT more stuff than I can even adequately describe. Just check out their page for more info.. I'll say I record my DX7s in Reaper and it works great.

P.S. 20 plus years out of music. What make and model of amplifier would be good to buy to plug the Yamaha DX7 into? A. MIDI ?
B. Tube ?
C. Solid state?
D. Tesla coil? O \
