Firstly great module although have to set everything really low to make it work BUT the oversample button seems to crash the unit once activated no matter on what setting
Cheers
You mean the CPU hits >99%? It should work with Oversample off or less than x8, though depends on the patch. And just making sure you’re on the latest 1.6.2 (not talking about the beta version, right?)
I’m working on the feature that gives you an option to allow the CPU to momentarily go over 100%, which should solve the issue where some modules spike in CPU when you change some parameters
Hi Dan
Using Firmware 1.6.2 ( is there a newer FW for the unit ?)
and plugins are the latest ones released (not the beta) no other plugins in the patch just the banjo and few inputs and outputs patched in .
everything works ok but as soon as the oversample gets selected it goes crazy and cpu drops out at 99%
Thanks for the response and no rush at all , hope youre having a great Christmas
Gave this a quick check, used auto map to set it up, no other modules loaded.
Auto map assigned oversample to the A knob, overload occurs when going past 66%.

Yeah, Oversampling adds a lot of extra CPU usage, it runs the inner algorithm multiple times, so the CPU load increases dramatically as you increase oversampling. Essentially, oversampling of 4x at 48kHz means it’s running the module at 192kHz. So you can see why it makes a huge difference in CPU usage.
At 48k/64 block size, it works with Oversample off, 2x, 4x, and 8x, but past that, it will max out the CPU.
So for MetaModule use, keep oversampling at 8x or less (assuming 48kHz). If you are using a Benjolin in a large patch and need to conserve CPU then keep the setting as low as you can handle in terms of sound quality.
A similar thing happens with the other modules that have oversampling (VCO Lab, Logic, PolySHASR, Reformation, ShapedVCA, VCO Unit, Wavefolder).

Got it, thanks! So it basically equates to, when mapping to a knob, restricting the max travel on the knob to just over 50% (51% works), that will keep it to the 8x maximum.
Yeah that’ll work, if you have Oversampling mapped to a knob, then make sure to limit it.
Yes, it’s definitely a unique module, and there’s an interesting story behind it. The original module was first developed by Rob Hordijk, who sadly passed away in 2022. Here’s a great video about the Rungler invention: https://www.youtube.com/watch?v=n_PgJ7BmGR8&list=PL-Px4uhLtNXUJ5MQ5GFUNaVqLvk57UQyL&index=21
