This app exist?

did this get released?

nice. ill keep an eye on this then.

I'm working on a cross-compatible HTML5 patchbook solution, too. That'll allow people using computers or non-android mobile devices the same features and total cross-compatibility.

I can't make any promises on the timeline for it but the back-end is already totally done. After the Android app hits the market and I'm happy with where it is I'll start looking at doing a web interface.

this looks really cool. im on ios though, bummer.

That is exactly what my current implementation is. I tried many other options like touch dragging and while that worked somewhat okay on my tablet it was simply impossible to be accurate on my phone.  For now you simply type in a row of hexadecimal characters and it draws the waveform, which is actually really fast and easy to do but makes for a sort of "boring" solution.

I've got a fancy new hexadecimal keyboard now that pops up for any hexadecimal inputs and it makes it very painless to type in your waveforms this way, so baring any "ah-ha" moments before next weekend, this'll probably be what you see for the beta release.

One last idea: since all waveforms have characters for each frame (0-F) that line the top and bottom of the waveform, wouldn't it be possible to enter the characters and watch a realtime drawing of the waveform for that frame? Since you are simply placing squares on a plane, it shouldn't be too hard. Monotonous, maybe, not fun, yes, but still better than me trying to drag squares all over a grid with my fingers.

Like I mentioned in the video, the beta will be out probably towards the end of the upcoming weekend, it'll feature pretty much everything other than the web features.

It'll hit the android market after a short period of beta testing.

Sweet! Great to hear. I can't wait for this app sir. Once I moved to android I was disappointed to find there wasn't already a iPhone lsdj patchbook equivalent.

I just added the "notes" input! A few people mentioned it and it's obviously a great idea. I've added independent note taking for instruments, waves and tables since they're functionally separate.

I'm also going to add a long-press action on the load menu to allow you to see the notes saved about an instrument.

This looks way better than the iPhone one. One thing I would love to see in this is a way to upload and attach a sample preview to each save so we could audition the sounds and know what each patch sounds like. I am fairly confident that most people, me included, can't remember what a lot of our old patches sound like just from looking at the name/tables/settings/etc. One thing that the iPhone version does have that is useful is a notes section. Just a little text box where we can scribble some instructions or something down, like "Best if used on note C5" or "This patch is meant to be  used in tandem with patch xxx"
And to answer one of your questions "should it store groove tables?"....YES. I have some instrument tables that have some specific rhythms that are designed around specific groove tables. it would be nice to store a groove to each patch or table.

I've already looked into parsing saves/lsdsngs and it's something I'd love to add after the core functionality is in place as it wouldn't be hard to implemement.

Longer names for instruments, waveforms and tables are already in place now but adding comments are actually a great idea!

The wave channel so far has been the hardest so far. It currently looks like the LSDJ wave frame screen and takes only touch and hex input. I've been using it a bit and it's very fast to enter values for waves that you're already created but maybe not optimal for general editing.

Hex friendly input method on the way!

I'd like to see:

- LSDJ save parsing, so you can easily rip instruments, presets, and wavefroms/frames (talk to 2xAA about his save explorer?)
- Longer filenames or in-file commenting, so we can be more descriptive with the names, or specific about how to use them (don't use below F4, sounds terrible)
- synth parameters for the WAV channel are essential, because some waveforms (like ones with tons of resonance) look crazy and aren't easy to replicate or draw, like a sine wave with low cutoff
- would be nice to see a hex-friendly numpad for entering stuff like envelopes and some other parameters

Looks great, kind of trumps my miniature-book patchbook idea haha can't wait to try this on my phone

Sound generation would be quite tough to do accurately and for the types of complex sounds you'd want to save patches for, accuracy would be important. I know that some people are working on reverse engineering the LSDJ playback routine and with that it might be possible to do via emulation, but until then it's not something I'd likely even attempt.

User uploaded sound is something I've given a lot of thought to as well but it's difficult to implement into my usage model. I want the app to be "quick and easy", there isn't currently a really quick and easy way of getting a nice recording of a sound from a Game Boy into an Android device.

That said, there's potential for the feature of including an audio example being part of the website.

Awesome!
