Today we are going to talk about the Roland SH-4d. Is this groovebox and multitimbral synthesizer based on subtractive synthesis, wavetable, FM synthesis, ring modulation and vintage synths like the Roland SH-101 or Roland Juno-106 the missing link between synth and drum machine. Can it keep up with competitors like the Elektron Syntakt or Teenage Engineering OP-1? Does it play in the same league like the new Roland Jupiter-X or even its conceptual predecessor, the Roland SH-32? It's really Bad?
