Roland SH-1000 Oscillator Waveform

[Riskteven]

Most transistor organs did the same to simulate the "reed type" stops

Very nice, my Korg Mini700s does similar things. Do you know what kind of OSC design that uses?

THANK YOU

What is the name or what you call that scope?

[Dovinia]

Very interesting video. Thanks for posting this!

Fascinating to see such crude waveforms; but they are no better or worse than other waveforms. Does the keyboard generate a CV? I suppose it's not a VCO.

[rolandsh1000]

it does generate a CV which is delivered to a very high frequency VCO that's then divided down to form the square/pulse waves that are constituents for the lower frequency oscillator waves.  yeah, the sh1000 is a weird and wonderful beast!

[karlkid333]

Ah, interesting. In this video I was reminded of the Crumar Performer, which has full polyphony. I believe it uses a similar divide-down technology, but I don't think it uses VCOs.

The SH-1000 sums 5 footages of square wave (32', 16', 8', 4' and 2') using standard resistor values to produce the 32' saw. The top 3 footages produce the 8' saw and the top 2 the 4' saw.

[rolandsh1000]

yup, that's what my service manual shows.

I just thought it was interesting to show how accurate the saw waveform was based on the tab footage setting.

it _seems_ to me that I can hear that the higher footage saws are more slightly more hollow (a bit closer to a pulse wave)

chique !
