this was the chart i found interesting, this human used a sine wave tuned to C to reference,
i don’t know what the OG pitch of ABAS ROM is. using any sample in any sampler as a reference and expecting it to be perfectly pitched is dodgy ground.
i don;t think the ROM machines can be viewed or used as rock solid melody makers.
