Hello audioz friends,
many years ago using the reFX QuadraSID plug-in (on MacOS 9), I created a double-octave up-and-down arpeggio…

Listen to it here:

Unfortunately, on newer systems that plug-in doesn't work and reFX hasn't updated it anymore.

Does anyone know of a more modern Mac AU plug-in similar to QuadraSID to create the same arpeggio?

Thanks for your attention and help.

 

That's a common problem with macs, there are so many different versions of the os and they're not very backwards compatible, old vst are almost always a complete nightmare on mac. But if you have the notes you played, you can just play it with any softsynth, tweak the osc to taste and add that delay? That timbre doesn't even sound like a sid so you should be fine with a modern synth, Quadrasid was never a authentic sid recreation like insidious or chipsynth c64, so dont worry about using a sid synth.

 

Hello @ElMoreno, the chipsounds has a very good Sound quality and a Arpeggiator:

Plogue - chipsounds --> www.kvraudio.com/product/chipsounds-by-plogue

macOS 10.11 or higher | Intel or Apple Silicon | RAM: 1GB or more | Disk Space: about 110 MB

chipsynth C64 --> www.kvraudio.com/product/chipsynth-c64-by-plogue
chipsynth OPS7 --> www.kvraudio.com/product/chipsynth-ops7-by-plogue

 

The problem is that, after so many years, I don't remember any notes!!!
I guess was the internal reFX QuadraSID Arpeggiator itself... it's possible? I really don't remember...
So now any help about notes is welcome to recreate that arpeggio.

 

Use a convert tones to midi utility? Anyone know one?
