Hello Adv Nilesh Agarwal, and about the issue you are reporting, depending on the hardware you are using there may be some latency that occurs from the hardware itself. In MixPad options, there is a feature to adjust the latency. You may want to check your hardware's manual to confirm which is the latency on that hardware and adjust the program to match it. In case the issue remains you may want to contact NCH Software support team for assistance.
