FS1R (capital R :P everyone makes that mistake) has the same screen * as used in the MU series and VL70-m, so no problems that I am aware of, especially not inverter whine since it uses (finally) a proper LED backlight. Still mildly irritating that it is a proprietary design (as in the AN1x: custom ...

I didn’t hear any particularly fast LFO in the first 2 minutes of the linked video. Again I wasn’t given any specific indication of what to listen for! Well, maybe the hardware LFO in the DX21 goes faster than the soft one in the DX7 – which would be understandable. However, I’ve never tried to max ...

Basically, have you looked in the manual for information on which parameters are accessible via MIDI?

OSCs by themselves sound pretty thin, that's obvious. An oscillator isn't responsible for a sound that is "thin " or "fat", the gain staging following it's output is what does. The osc only provides the initial waveform within the predefined voltage range; that's it. A "shape" to start sound-design...

Please define “more aggressive and powerful” so that we know what we’re talking about. Anyway, I can think of 2 possibilities: * Your cited examples on the DX21 are using non-sine LFO waves, which the DX7 lacks (DX21 is hardware LFO in the FM IC; DX7 is software) * Perhaps the DX21 has a higher maxi...

Interesting, I remember reading about these sorts of mods before but forgot them. In the meantime I have accumulated several old synths that might benefit from such shielding. But assuming the humming ‘issue’ is purely acoustic (i.e. no risks to user or product lifetimes), it can be bearable – and p...

probably just anti-short precaution, against the metal chassis and/or hasty users who open the underside? I have worked on keyboards that had that sort of flexible foil over large PCBs. It probably is not actually needed but good to keep if you had it. Someone more trained in techy work will have a ...

Yeah, but as the same link also explains, the non-headphone ones are somewhat compensated by having digital volume controls, meaning that induced clipping – which results from (both models’) crappy botched DAC implementation – can be averted simply by turning down the dial. The with-headphone model ...

so, yes, assuming your two devices offer respective clock master/slave options.

velocity is completely unrelated.

Playing Devil’s Advocate here… How do we know the sale last year didn’t fall through, and the seller might have decided to keep it until now? Not that I would recommend anyone going near it until the seller provides a new photo with a current newspaper in it – just to be safe. I called someone out o...

You need to read around for any settings related to turning Control Changes on/off, and/or making them global on 1 channel (presumably not the same one you are currently for notes) only, and change these to be appropriate to your needs.

Yeah, don’t skimp on safety where AC is involved. This comes after I got a nice sizeable jolt from a PSU board I had tested as faulty and then unplugged earlier today. In retrospect, it was moronic to handle it without looking at what I was touching. But these things are easy to forget if vigilance ...

Great! Yeah, I always have mine on "norm"[al], so each voice receives independent CCs on its own MIDI channel. I struggle to think of uses for Global (or an overall "off", to be honest), but I'm sure there are several. Enjoy! The TX802 is a lot of fun.

…the “shelf type things” are racks. :? The synths and other things that go in them are described as rack-mounted , not “racks” themselves (that is, at best, an informal short-hand term) Synths for rack-mounting are all (or nearly all) designed to the 19-inch standard. Search for that. It’s not just ...

Did you definitely check the earlier SYSTEM SETUP > 1. MIDI Receive > Control change? See page 8 of the manual. In particular, if off (obviously) or set to a Global channel other than the one of your keyboard, CCs will have no effect.
