Open Sound Control for the TMC-1

After publishing my initial idea's for a tablet interface to the TMC-1 using HTML, one of our users (James Chappell) suggested that I look at TouchOSC. After investigating OSC I have shelved the HTML interface and spent the past week developing an OSC interface.

The main advantage of using OSC is that users can design their own interfaces incorporating only the functions that they need, simplifying the user interface. Multiple pages allow for different applications. OSC applications are available for IOS and Android I have not found any for OSx or Windows.

You can see the two test interfaces I designed below The first includes input selection (user keys), metering, output level control and Level indication. It has been designed fot the TMC-1-Penta which can select between 8 inputs. I was impressed with the meter performance using an old Android tablet.  A nice touch is the battery status indicator


The second screen below is a cue source selection page complete with level controls and enable keys, This design may be used as a template and unused input and output controls deleted.


I have now finished two more test pages and I will be releasing this software for the TMC-1-Penta, -XMon and -AMon later this week - I also found how to label the tabs!


For the TMC-1-Penta only - Note :the latest Penta software has 32 Palette entries instead of 16.



The images above were taken from the design s/w, the Tablet and my phone look the same or better.


TMC-1 with tablet in my workshop - designs for the 3d printed cradle are also available.

Initially I intended  to use OSC-Midi commands but then decided to use direct OSC commands to control the TMC-1, if the controls are named correctly they will connect directly with the TMC-1. The user can define the label names but it is recommended that the TMC-1 updates User Key labels as they can be dependent on the interface (Penta, XMon, A-Mon) and can change when the s/w is updated. All controls are updated when the page is changed, the interface is bidirectional and updated in real time. The meter block uses a multi-fader graphic.

I am currently controlling the TMC-1 from a tablet and phone simultaneously.  The first command on either will update the display tothe current TMC-1 status. The [TMC-1] key is used to re-sync the display without change. To reduce Ethernet traffic I meters are only activated after an initial touch, as not all designs will include meters. Ping should be enabled with a 10 second delay to keep the meters running.

Push keys are made from three elements, the key, the label and the LED for status indication.
The cue routing keys are Toggle buttons that include on/off indication. The meters are made using a multi-fader. SPL indication is simply a Label. TouchOSC is available to download for $5, the design software is free and available for both Mac and PC.

I envisage other stand alone applications the firmware outside of the TMC-1, for example controlling Mic Amp's, GPIO, or Older Midi instruments from tablets or even mobile phones. Next week I will be releasing OSC enabled versions of the TMC-1-Penta/XMon/A-Mon as well as at least two templates.

For those who may wish to check out the beta test software a design package which includes firmware for the TMC-1, 3d designs for a tablet cradle and templates is available here-
