The FM oscillators of FM-X and HALion/FM Lab are the same, but there is no straight way to dump the settings to HALion. Furthermore, the architecture of MONTAGE, e.g., the effects, up to eight elements, the modulators, etc., are too different from HALion/FM Lab. Important settings will get lost if you import just the oscillator.
You can read out the settings of the FM oscillator from the display and transfer them to FM Lab and it will sound the same. But, that’s only a workaround and the modulators, etc. would still be missing.
There are much fewer sounds available (free) for FM-X than for DX7 or TX81Z.
Therefore, we decided to support just DX7 and TX81Z SYX files, which are the most common and most important formats. And, you get tons of these presets from the internet.
