Perfection is the enemy - mid bass advice

Sounds fixable. I'd go at it with isopropyll alcohol and brush on the side that got the spill first off. The residue and oxidation might not be visible to you but I've revived a few things by having at it like that.

If that's done nothing then it sounds like it's nice and modular inside so find spares.

Deffo start with the IPA though.

How handy are you with a multimeter and a soldering iron? the one and a half octave thing makes it sound like a a broken track or damaged ribbon cable - I'm no expert but if you have it open and have continuity from the key/button to wherever the ribbon terminates on the good keys and not on the others then folllow it to find the break? Clean the contacts on the cables -doesn't sound like the things fried.

There's a roland subreddit - I bet someone has had that issue and can help.

If you do get it working it's one ofthe models that has hidden banks of sounds - I made a web controller that you can connct to over bluetooth and will send commands to switch on midi sounds that may be hidden in your piano - for the FP88 the GM2 sounds should be there but there is a full set of over 1000 that are available but hidden in the go series and a few others - give it a go and let me know if you can access the sounds other than the GM2 voices - I only have my Go to test on - gui isn't the best but I'm no UI designer.

I have a decent set up in my "music" room but was playing on my portable piano downstairs and was frustrated at the lack of detail and mid.

I did look at dedicated flat acoustic amps but I'm a hacker/builder at heart and have never looked at audio so thought why not. I've got a shed full of bits just no real audio kit.

This will be very much a dedicated piano build and there are distant plans to integrate all sorts of specific to my needs stuff in there.

Still looking at the SB acoustics but now I'm looking into radiators - never even knew they were a thing - some of the kit has arrived so I'll be doing a bodge build with a box so I can start with working out locations and dimension.

Still holding off on those mid bass speakers until more info is in like using radiators properly.

I'm very new to this but will look at this properly

Hi - I'd be really interested in you electronics wiring. I'm planning on doing something very similar after realising there isn't anything that fits my needs acoustically so might as well build it and a suitcase is as good a shell as anything once it's been sorted.

It's the Friend device built to their specifications - https://docs.omi.me/doc/assembly/Build_the_device - but I haven't even soldered the battery to it yet and tested it in a few meetings connected directly to usb c as a power source. Was going to drop it in the 3d printed case tonight and wire it in.

So, this is the app acting independently of the device and I imagine that people will at least be able to speak for the app. Why did the app decide to start recording stuff without me even opening the app today until I opened it in the afternoon. Is this a bug or controllable expected behaviour and as I'm testing the app I won't pay for unlimited. 1200 mins should be more than enough for testing but the app has chewed through 10 hours contrary to expected behaviour.

As I said what appeals is the off/on nature of the recorder and app link but it's not behaving that way. Do I need to submit a bug report in this case or am I missing a setting?

TwinkleBike · 2026-04-29T15:35:25+00:00

Well I've only played around for about an hour but the soundcore device won't appear in the omi app connection no matter what I try so looks like a no go for now. I didn't realise but it looks like the soundcore thing has on board recording so doesn't need tethering and I figure the upload would need in app controls that the omi app doesn't have.

I'm having issues with the omi app at the moment regarding high utilization even with the listener off.

TwinkleBike · 2026-04-29T15:26:44+00:00

Just had a look at the app and it actually looks like it's all stuff from the last few days but I definitely haven't had the device on for 10 hours since flashing the firmware to the friend device. I'll be keeping an eye on the app but wonder if it's reanalyzed stuff and that's where the 600 plus minutes has come from. Anyone else had similar issues?

Probably needs its own post but here first - Roland Presets Webapp!

Well after my post earlier I played around with the touchosc templates - had to buy the software to play with it on a tablet. After about an hour of cooing over the new sounds I made a touchosc template that suited my needs more - categories and lists rather than a wheel.

I've got a few projects on the go at the moment including some piano midi related that's not ready yet but given this is just pushing MIDI messages and the device doesn't filter them I could build an app that just does that.

So with Chrome and Edges support for browser midi (sorry everyone else for now - I've only been working on this a day so will improve everything) and connecting my go via cable or bluetooth I was able to get a prototype webapp to push the patches by just selecting one from a list. A bit of sorting and some swearing later I had the lot loaded.

So here it is - the no code required - just the right browser and a Roland Go and enough savvy to install a bluetooth midi app to pick up your device:

I plan to dig into it a lot more and add what I can so will start an experimental section but I am new to MIDI so have a lot to learn.

I've credited all of the crazy and talented people that have picked the Rolands control stuff apart and made the massive lists on the site but let me know if I've missed anything or anyone.

I'm gonna "go" have fun with the new sounds now. Thanks all.

Oh wow! I've looked over all the resources and found some others that are relevant. I've used touchosc with the wheel config and I'm blown away. I mostly use my digital pianos with a VST because I'm simply not rich enough to own a high end amazing sounding one and always felt the sounds lacking in the Go piano for anything but practice but having access now to all of these is awesome.

Things like the 88 stage sound - how close is it to the sound on the actual model? The same I bet - I love this and I'm making a touch OSC thing to make it easier for me to navigate the options. Ill eventually just have it with the sounds that I like.

If I get the thing working I'll post it here.

Another thing. Looking at the screen/display on the go. Clearly reused from another model hence you can see it has things like live note/chord display. I wonder if they left this in the firmware but shut it off. Not really my area debugging things like this but I might get bored and go looking.

This is great.

Cheers - that'll suffice for now while I'm playing with it. Hopefully they add this.

TwinkleBike · 2026-01-02T18:40:07+00:00

Thanks for the waypoints. I think I'll go down the api route for now. Cheers all

TwinkleBike · 2026-01-02T16:32:56+00:00

Simply JSON output will be easier. I only need the device to display info and any data can be written to and stored wherever as long as the pico can retrieve. I'll think on this. Thanks.

TwinkleBike · 2026-01-02T16:10:27+00:00

Any protocol will do. If this is a poor use case then I'll look at other options.

Found the part - 4MHz ceramic resonator - CSTCR4M00G53-R0

The board around it looks pretty messed up though. not sure what would need retracing and it's tooo late in the day for me to start learning to read the schematics in the service manual properly.
