Maj7 sounds bad
So do Aug, and diminished chords
When using synths when I make a track…I guess because of the harmonics and the tones…
As for minor and sus chords sometimes yes and sometimes no
Drum, bass, and power chords work the easiest and are quicker…
But Unless I play around with the fundamental tone and key modulation…the jazz chords sound dissonant…
The most success I’ve have was to start of with a chord like E and break up the chord by having an individual element play a note from the chord E and develop a progression with one element soloing while another element varies the chord progression sequence and bass just follows…I suppose I could make complementary progression for each element i.e. by certain element play complimentary scales while others sustain the key or something…
