Would advice usage of vibrato and slide-ins/outs for extra spice. Maybe different pulse widths for the different sections helps as well
A melancholic 12/8 track created using both the 2A03 (DPCM channel goes used) and 4 PCM channels from OpenMPT, taking inspiration from composers like Shinji Hosoe. All of the PCM instruments were taken from Korg M1, except the birds sample which comes from Zero-G Datafile 2. I also added some post-processing such as panning, delay and mastering.
