Dexed doesn't read DX7II or later cartridge. The data is always corrupted.
For now Dexed only works with the original Mark I cartridge, supporting the extended version means also supporting the storage which can be more tedious than expected.
If you need to work with those extended cartridges, you can use http://dxconvert.martintarenskeen.nl/ that can convert most of the DX familly cartridge to the DX7 Mark I.
The installer didn't update the dexed version, how can I confirm that it is installed
It is strongly suggested to delete or move the plugin before running the installer. You can click on the dexed logo on the lower left, it will show the about box.
Does Dexed works on OS X 10.6 ?
No, Apple makes it difficult for us to release new software with this old OS version. You can use an older version of Dexed that supports this Mac OS version : dexed-0.9.0-osx.zip
Does Dexed uses the same midi velocity range (0-100) as the original DX7 ?
No, the envelopes are based on the DX7II that are using the standard midi velocity range (0-127).
Some notes seems stucked and/or generate sound indefinitly, is this a bug ?
The envelopes on the orignal DX7 can be programmed to played indefinitly. If you want to avoid any stuck notes, be sure to set L4 = 0 and R4 = 99.
How can I find help/contact the author ?
If you have a generic question, you can use the kvraudio dedicated thread for dexed. If you have found a bug, use the github page to open a new issue. I'm asb2m10 on kvraudio.
Programmer/dsp enthusiast: I was expecting floating based 0.0->1.0 DSP stuff but when I read dexed code, the only thing I see are bit shifts and adds. What is going on ?
msfa / Dexed is an integer based synth engine, it uses the Q** format.
