Hammond Super B – Latency Tests


Scope is a Fluke 99B 100MHZ digital. Using single trigger with hold. Measurements are MIDI as it leaves the Super B and Audio from Computer Sound device. Kore 1 Controller with built in USB Sound. Any delay from when the key is pressed and MIDI is output is NOT measured here. Set to 10ms per division means each square box on the grid is 10ms. Triggering is set to -4DIV which is why the signals are starting closer to the middle of the screen.

B4II freestanding using ASIO4ALL driver with the Kore 1 USB Audio.

Super B - Latency Test

This first shot shows right at 10ms Latency

VB3 running in VstHost (free software) also using ASIO4ALL.

Super B - Latency Test

This looks like a little over 10ms Latency.

B4II running in Kore Host with Kore ASIO driver.

Super B - Latency Test

Exactly 10ms Latency

VB3 running in Kore Host with Kore ASIO driver.

Super B - Latency Test

Looks like about 12 ms Latency

VB3 running in Kore with ASIO4ALL driver.

Super B - Latency Test

Slightly over 10ms Latency

B4II running in Kore with ASIO4ALL driver.

Super B - Latency Test

This looks like it is a little less than 10ms Latency


Conclusions

First of all these different setups were very near 10ms which may just indicate what this computer and “soundcard” are capable of. It seems that when a difference was evident, that B4II was slightly quicker than VB3. Secondly, it seemed that ASIO4ALL was slightly quicker than KORE ASIO drivers. I plan to try using ASIO4ALL for awhile to see if I feel any difference in my usual setup.
