Juno60&Juno106vsJupiter8

[Solderman]

Take this for what you will, but it always bugged me that the Juno and Jupiter were nearly the same size, yet the Juno is so much more limited. It always bugged me, anyway.

Someone was talking about how much warmer and more pleasant the JP8 and Juno 6/60 sound than other Roland polysynths with the IR3109. I can't remember where I read it, but it seems the highpass filter used by both, which is after the voice mix, is partly responsible for this desirable tonality, regardless of its cutoff setting.

Don't know about the earlier Junos, but in the 106, they left room for the power amp and speakers for the 106S/HS-60 configuration. And, that was about the time when miniaturization of the electronics was approaching the point where the panel space required for the controls would exceed the internal room needed for the circuitry.

The highpass filter thing was something I started. Here's the deal: The Juno-60 and 106 both use a set of passive RC circuits for the highpass filter (the IR3109 is not used in the highpass filter). On the 60, highpass position 0 is bypass; positions 1, 2, and 3 bring in progressively higher cutoff frequencies. On the 106, position 0 is a bass boost. Position 1 is bypass. Positions 2 and 3 are high pass with 3 having a higher cutoff frequency. I don't know for sure that this accounts for the tonality differences between the 60 and the 106, but it's the only audio circuitry difference that I know of between them.

I haven't looked closely at the Juno-6's highpass filter, so I can't say much about it. I know it's continuously variable rather than having the four settings. IIRC, on the Jupiter-8, the VCFs are switchable to high pass mode; there isn't a separate high pass filter.

How about getting a second Juno 106 - or perhaps better? a Juno 60 with a MIDI retrofit - and MIDi the two together. It won't get you a Jupiter, but it will get you a two oscillator Roland polysynth, and having two independent filters could be interesting.

Alright.I got the Juno 60.





Now there is a new dilemma, do I need JP8 having those two?

It would be interesting to do this, had anybody such an experience?

[THEODICY]

Yes, me. And there is this:

Such a great filter in the 106. Really cool to hear how good two of them in parallel are at vocal formants.
