Engine resolutions
------------------
Dexed can be configured to try to use the original math limitation of a DX synthesizer. And when I say
math limitation, I'm not only talking about the DAC, it is also about the sin LUT lookup table, multiply
resolution and original DX sampling rate. This is a work in progress and this might take time to be able
to perfect.
If you look at the original DX7 and implementation a DX engine with 10-bit sin lookup and 12 mul possibility,
you get something "not quite there". Yamaha did a lot of hacks to be able to squeeze this into something
musical and expressive. It is those 'hacks' that we need to recreate to be able to find that original
DX sound.
Engine Type
-----------
Dexed can be configured to try to use the original math limitation of a DX synthesizer. This does not
only apply to the DAC, it also involves the bit resolution of the sine waves and the way that the
amplitude is applied to each operator. Since all of this is experimental, multiple engines will be
available to be able to compare them easily.
Dexed comes with 3 engine resolutions :
Dexed comes with 3 engine types :
* Modern : this is the original 24-bit music-synthesizer-for-android implementation.
* Mark I : this is a pale implementation of the limitation of a Yamaha DX7 Mark I with the 12-bit (with the 4-bit attenuator hack) DAC.
* OPL Series : this is a experimental implementation of Yamaha 4-ops that used the YM2151 chip. These chips were supposed to be even more limited to the DX7 but gave a very interesting distinctive sound.
* Mark I : It is the music-synthesizer-for-android implementation reduced to 8-bit. It is used to be able to see the difference between the OPL series that also uses 8-bit but with sums of logs to avoid multiplications. It will be upgraded to 10-bit/12-bit later.
* OPL Series : this is an experimental implementation of the [reversed engineered OPL family chips](http://sourceforge.net/projects/peepeeplayer). 8-bit. Keep in mind that the envelopes stills needs tuning.
Using as a DX7 editor

### Troubleshooting
* If you play on your DX7 keyboard, the |DX7 In| light should be flashing. Use this to test the midi in communication.
* If you click/play on the Dexed virtual keyboard, it will send the corresponding midi out note to the DX7 port; if configured. Use this to test the midi out communication.
* If the data sent is corrupted (wrong checksum, DX7 crash), it might be the midi interface implementation. Default Windows USB midi driver are known to send corrupt sysex data. If it is the case, use a third party device (like the midiman uno) that have his own USB driver.
* If you are unable to open the interface (error message after the using the [PARM] dialog), it might be because the midi driver doesn't support multiple clients (common on Windows). Be sure that there are no other applications that are using the same midi interface.
