This thread is intended to gather the feedback of Orba tinkerers.

Also one thing I've realized about pitch bending (Index 23) does not implicitly control the bend range but rather the starting tone in cents. Setting it to 0 lowers the starting note therefor giving a larger bend range. If you play a note from one of the altered bend patches then a normal patch immediately after you hear that the altered patch isn't really in key.

In the meantime I've had an idea.

1) Create a script to send "q" to console and bundle it with Chordfiddler 

2) Put out an ad

"New Orba-Q unlocks the power of your Orba-1 with the power to add quantisation to your loops as well as customising chords and scales! Introductory offer for only £20. Please send payment by Paypal to BJG145@......"

(...just kidding. Then again...)

>"Not quite. Each Chord Pad cuts out the next."

I hadn't noticed that. The Tap gesture for chords has different seekerData with its own index (11). I ghuess this is the "Chord Event". This updated table includes a column taken from Faux Chords. I think other things like gestureUuid and ModifierData are the same.

...also note the change from 8 to 32 in row five. Maybe that's connected with the polyphony.

(...the last two values in the column are 0,0 like Tap Lead...)

...just some notes on attempts to boot/flash the Orba in a streamlined configuration.

The main PCB has three microswitches operated by the power/vol controls, and connections for:

1) Speaker

2) Power

3) Motor (vibration)

4) Sensor PCB

Unfortunately I've damaged these so I can't test fully.

In general, the Orba can get into four states:

1) Powers on normally

2) Unresponsive but can be automatically recovered by the App in DFU mode

3) Unresponsive but can be manually recovered by the App in DFU mode

4) Broken

The most signs of life from my PCB are with (3), described in Artiphon's notes on recovering an Orba from an unresponsive state by downloading a new copy of the firmware.

What happens is this:

1) Run the Orba App and navigate to Settings

2) Connect the PCB and boot into DFU mode

3) Drag firmware file to App as per the instructions

Either it's waiting for something that's not connected, or it's otherwise damaged.

As @Tony points out, the touch sensor PCB has its own IC which seems quite sophisticated. Perhaps the "capsense bootloader" file I mentioned gets sent to that.

It's not very clear how functions are divided up between the different ICs, and it would be difficult to try and figure out how to work with it. From Googling, it sounds like it may be in a configuration where the ESP32 is a "slave" and the STM32 is a "host MCU". I'm not sure if it's possible to talk to the ESP32 directly in this hardware or whether everything is relayed by the STM32.

I'm still curious about the kind of direct communication that takes place between the App and the Orba when changing key, but I don't know how to try and decipher that, or even which IC the App is talking to.

"Also note the change from 8 to 32 in row five. Maybe that's connected with the polyphony"

...after all, the chords have four notes...makes sense... 

...just flipping through some of the stuff in that downloadable firmware Orba_Fw_0.15.13_PreRelease zip file that Artiphon provides for recovery.

https://storage.googleapis.com/artiphon-web-content/Orba_Fw_0.15.13_PreRelease.zip

Interesting to see some of the comments in the "Changelog_Beta" file, like:

- Fixed issue where notes would disappear with quantize and cause a crash (PROD-2511, PROD-2528)

- Quantization is turned on by default (constant length, snap to 1/16 notes) (PROD-2130)

- Various bug fixes with quantization (PROD-2447, 2174)

As I mentioned, the XML in the song files contains some quantisation settings. This is from 1981.song.

<Mode name="Bass" quantizationMode="0" volume="200">

It sounds like there could possibly be some slightly broken quantisation features that might be accessible with some XML hacking.

Hi all, 

Just get my Orba and also new to any musical instruments, having read via the forum and found some guys are able to make presets themselves. I would like to make preset with sounds like basic wooden guitar, can anyone throw some lights to me?  Sorry if the question is too dumb.

The currently available release is 0.15.13. Reading back through the changelog:

0.15.1   Disables quantization by default

0.15.0   Quantize on by default

0.14.19  Quantize on by default

0.14.18 - Quantization is turned on by default (constant length, snap to 1/16 notes) (PROD-2130)

etc

I don't suppose these earlier releases are still available, but maytbe some functionality is still there if the XML can turn it on.

I've been flipping through some of the old versions to see if there's any new XML. v13 had the quantise options in the save dialog, which adds the "groove" mode 2 you found to the XML. I haven't heard anything groovy yet.   

One of the improvements for Orba 2 is bar length from 8 to 128. According to the change log, "Limit max loop length to 8 bars" was new to v13.18 but I haven't seen how to increase it in v13 yet. There's "nBars" in the app code and the XML.

I just Googled the inscription "Reply hazy, try again" on the motherboard; haven't come across it before. It's apparently from something called the Magic 8 Ball.
