Very small improvements make a huge difference in this realm. The % amount of latency improvement of buffer reduction is not that much midiwise I’m stymied by something that isn’t even a technical limitation, but is instead artificially imposed by the UI. I discovered after delivery of an $800 iPad Pro M1 and interface that I bought to integrate MIDI GUITAR into my live rig. Being hardcoded to a lowest-common-denominator setting sucks on a fast device. You could put it under an “Advanced” section and/or warn users about changing it. It’s makes little sense to have the same buffer on an A7 and M1 device. We locked it at 256 in the standalone basically to have a smooth user experience over a wide range of iOS devices. Maybe on a more modern iPad with more powerful CPU (mine is a 2016 iPad Mini 5) you could have more synths open with a 128 buffer setting, I’m not sure. Getting the buffer size down reduces latency to the minimum and makes your playing experience far more satisfying, so for me it’s worth sacrificing having lots of synths/apps open to be able to use it. On my iPad I can have a couple of synths open in Audiobus with this setting before getting any crackling - but just one is safest. First open a synth in Audiobus, then open MG2. Open Audiobus and set the buffer size to 128. You can even close AUM and the 128 buffer setting will be retained in MG2. They will be set to the same buffer size. You can either play inside MG2 with this setting, or outside synths. If you open AUM and set the buffer there to 128, then add MG2 (included in the inter-app audio list) in the chain after system audio. I’ve noted that MG2 defaults to a buffer of 256, but also found that it can be reduced to 128 in a couple of ways: Can you be more specific? For example, how much faster will C5 convert than C3? I assume this means that higher notes will convert faster than lower notes? However, it doesn’t seem noticeable to me, so it must be a very small effect. The conversion speed is not related to the speed of the CPU: it is related to the wavelength of the notes involved.
