AirDeck Project Update 2.0

The Fall Quarter will be starting up this week and as a result I am really making a final push to complete as much of my project as possible. My goal over the summer was to complete as much of the application as possible, so I wasn’t scrambling during the quarter to wrap everything up. The good news is, I have made some significant progress on many fronts, but I am still not where I wanted to be when the quarter started.

Here is where I am at so far:

  1. I have redesigned the GUI somewhat, adding elements for some of the features that I am adding. For example, I added tabs to select the mode the AirDeck will be using based on user selection. Right now, my main priority is on the “SynthDeck,” which is the theremin app. I added tabs for ScratchDeck, a DJ scratching utility and MixDeck, a DJ mixing utility. These last two components are outside of the scope of my Project, although I would like to fit them in, time and resources permitting. Even when the Project is complete, I still plan to develop these elements… I Just had to limit the scope of my project work to something that I am 100% confident that I can deliver – which is the theremin/synth side.
  2. I have the MIDI out working now. This will allow the user to select a MIDI out device and it either can use the built in General Midi Instrument library(from the soundcard), or it can be used to control an external sound source such as a VST instrument, a 3rd party synth application or MIDI capable keyboard/gear. One issue I am trying to work through is that because I am using the MIDI pitch bend control, which is a variable parameter depending on what MIDI capable device is being triggered, the notes on the keyboard grid do not line up with the grid that I currently have set up for internal synthesis. So I might have to dynamically reconfigure the keyboard grid depending on the range of notes the pitch bend is set for, although this is dependent on the external application. I did include a dropdown menu for choosing the General MIDI patch, so the user can change the instrument they are playing. Currently these are represented by numbers, if I can figure out how to get the list of instrument names programmatically, I will add that as well.
  3. The amplitude control issue has been resolved, although I need to work this out for midi control. It is my understanding that midi control has aftertouch and velocity signals that can be modified, so I need to figure out how to dynamically control these.
  4. The GUI has been tightened up in terms of event logic. I have individual methods for each of the GUI components such that choices made by choosing certain items make the appropriate calls.

Here is what is currently outstanding:

  1. While I added synth parameter sliders such as Attack, Decay, Resonance, etc. I still need to figure out how to program those to apply the actual effect.
  2. Same thing with the effects sliders, which will add global effects such as Reverb and Delay.
  3. I need to program the preset sounds. I want these to sound as realistic as possible and since I am still learning a lot about analogue synthesis, it will remain a challenge to program these right.
  4. I want to incorporate patch saving capabilities so that a user can tweak certain parameters of a sound and then be able to recall these later. That is why I have added a File Menu.
  5. I want to add status indicators that show the three following things:  a) the Wii remote is connected, b)battery level of the Wii remote, c) Midi out is active.

Here is the GUI as it currently stands:
