Hello, guys! I am tring to play something in OpenMPT. I try to use on the the default instruments from MIDI Library. It is ok with one called "Church Organ" and "Acoustic Grand Piano". But then it comes to Synth Bass - https://youtu.be/HsrJqDj80mM (https://youtu.be/HsrJqDj80mM) here is the video of my problem. After dragging and drop to Instruments tab Synth Bass change its sound. Is there any way to make it sound like in MIDI Library?
There is a mapping error in the MIDI library preview. The sound you are hearing is Organ 2, not Synth Bass 1. For the time being, open instruments from the GM.DLS tree instead of the MIDI Library tree to get the correct preview - or even better, don't use those instruments at all, they are provided by the operating system and aren't very good.
The MIDI library preview was fixed and will work correctly in the next OpenMPT update.
