You need to turn on the Scale Lock option in the MIDI Control preferences, then any input on "white key" notes will be translated into notes in the currently selected key and scale.

Yes this works with all the preset scales.
However, It doesn't work when the scale has
alternate tunings ie: -30 cents. Again,when I use my
iPhone to trigger the keys then the the proper
tuning(pitch of the note) is heard. But when using
A midi controller to trigger the external sound module
scale lock works providing there hasn't been any
deviation from 0 cents for any of the pitches.
Middle eastern music works with quartertones.
These quartertones can only be sent directly from
The iPhone to the external sound module and not the midi keyboard controller.

Any ideas?

Oh wait, you are trying to use an external keyboard as input to TJ, apply Scale Lock for the MIDI thru capability to go back out to your external sound module? In that case, you are correct, it looks like only midi note events will be output and not any custom pitch bend messages that might be required to get the external sound module to reproduce the altered tuning of the scale. That was an oversight on my part, and I'll try to correct it in a future update.

And yet if I play thumbjam directly on the iPhone, the altered tuned notes are sounded om the external module properly. In other words the external module responds to the user tuning of thumbjam.

I know, the oversight is that the *MIDI Thru* feature does not produce the pitch bend messages whereas the normal TJ touch control does.

Ok so update please :)
All the best!!!

I am having a problem using iFrettless bass as a controller with Thumbjam.
The pitch is off even when I use the chromatic scale.

Any ideas?

Thanks

Greg

I just replied to you in an email:

You just need to match up the pitch bend range in both apps. In iFretless, in the midi settings swipe to the second page, choose channel Omni, and set midi bend up to 12 (for best results), and choose octave you like. Then in TJ's Prefs->MIDI Control, set Pitchbend Range to 12 also. I tried it and it sounded right to me....

Hello,

Has Thumbjam been updated to provide the function
as I questioned in the post above? Thanks for any info.

All the best,
atoori

Maybe as an incentive I thought I'ld mention. With this added feature alone, Thumbjam would
attract a huge ethnic community of keyboardists interested in alternate tunings
for their external hardware. :)

Has this feature been added in the latest update? Still unsure.

No, there has been no update since you asked the question. There are many irons in the fire and TJ's turn has not yet come around again.

When I use the scale lock on external hardware I hear both the chromatic scale as well as the scale assigned
within TJ. For example if I select major pentatonic when I play my keyboad I hear harmonized notes. Not Pentatonic scale only. Where has my configuration gone wrong? I use Irig midi and have midi in to out and out to in.

Any suggestions why I hear both the new scale and the actual keys when playing only the white keys on the keyboard? IE:TJ selected scale is C Harmonic Minor but played on the white keys of external keyboard sounds out both a C major scale and the locked scale of C harmonic minor.

I need you to describe exactly what your setup is, eg what hardware, what you are plugging in to the iRig midi what options in TJ's input and output connections, what midi channel input you are set to, if Omni is on, and whether you have a second instrument loaded in TJ.

Edit Update: Local Control was set to on. Local control off solved the problem! Now, one more question :)
When using TJ in a live setting can the Input Scale Lock be assigned a midi message? To quickly alternate between whatever scale has been selected in TJ and the chromatic scale to play the keyboard in a standard chromatic scale?

Ok you got me thinking it through a bit more. I am hearing a double(unison) chorusing sound
of ie: the piano patch on my keyboard. Suggesting the midi note on message is doubled if that makes any sense.
TJ settings:

Use CoreMidi=ON
Active in Background=ON

Output Options
Send Pitchbend=ON
everything else OFF
Channel Start 1
Voice Channel Start 1
Channel Per Touch OFF
Channel Range 1

Input Options
Input Scale Lock ON
Omni Mode OFF
Use messages all OFF
Enable THru Mode ON
Channel Start 1 (If I set this to any other channel, I hear my external keyboard play only the white keys that are being played. When set to channel one I hear both the white keys and whatever scale TJ is locked to)

iRIG MIDI OUT ON
iRIG MIDI IN ON

External Hardware is a Yamaha MOX (Motif series) keyboard

Basic Receive Channel = 1
Keyboard Transmit Channel = 1

Thanks for your time in advance!

Best regards,
Ash

There isn't a CC or anything to toggle on/off scale lock, although there should be! But there *is* a way to switch between the quickswitch buttons using a bankselect and PC message. If you bank select to bank 2 (zero-based counting, eg: 0, 1, *2*) then program change messages will select the key/scale combo at that slot in the current quickswitch buttons. It doesn't give you chromatic, but at least you can make it interesting.
