Mario, I’m curious what info source is telling you that the Tascam 208i is not multi-client? I’m observing the opposite.

According to AI:
Yes, the Tascam 208i is a multi-client audio interface. This means it can handle multiple audio streams from different applications simultaneously, allowing you to run several audio programs at the same time without conflicts.

When I say the Tascam 208i is a multi-client audio interface, it means that the interface and its driver software are designed to handle multiple audio streams from different applications simultaneously. Here's a breakdown:
1. Hardware: The Tascam 208i hardware is capable of managing multiple inputs and outputs, which is essential for multi-client functionality.
2. Driver Software: The driver software provided by Tascam for the 208i supports multi-client operation. This means that the driver can handle audio streams from multiple applications at the same time without conflicts.
In essence, both the hardware and the driver software work together to provide multi-client capabilities, allowing you to run several audio programs simultaneously and route audio efficiently.

Tascam designed their own custom driver software for the Tascam 208i. The driver software is specifically tailored to ensure high stability and reliable performance for their audio interfaces. This custom driver allows the Tascam 208i to handle multiple audio streams from different applications simultaneously, providing multi-client capabilities.

Tascam's custom driver software for the Tascam 208i is called the TASCAM Control Panel. This software is designed to manage the interface's settings and provide stable operation with low latency.

A popular audio interface that is not multi-client is the Focusrite Scarlett series. While these interfaces are highly regarded for their sound quality and reliability, they do not support multi-client operation. This means that only one application can use the audio interface at a time, which can be a limitation for users who need to run multiple audio programs simultaneously.

According to Tascam Tech support: He said he wasn’t familiar with the term “multi-client” but he said the 208i will smoothly handle any number of audio applications that are running as long as those applications do not have “exclusive control”.

According to my gear advisor: All 3rd and 4th generation Focusrite interfaces are multi-client. He had no experience with the 208i.

According to the Guitar Pro User Guide : Choose among the plugged devices. We strongly recommend using an ASIO device on Windows. The ASIO drivers are vital to use the Line-In functionality in Guitar Pro, and to get the best out of the application in general. On macOS, the CoreAudio drivers are used. ASIO (Audio Stream Input/Output), developed by Steinberg, is a cross-platform, multi-channel audio transfer protocol that is being adopted by many of the manufacturers of audio/MIDI sequencing applications. It allows software to have access to the multi-channel capabilities of a wide range of powerful sound cards.

According to me: Attached is an overview diagram of my configuration, I should have built this diagram years ago to organize my info. All the music software shown (with proper settings) can be running at the same time. When Guitar Pro had incorrect settings Studio One had a problem. But the Tascam could seamlessly move from one program to the next. In the case of Guitar Pro, I think its device got incorrectly changed by a software glitch during an upgrade.
If anyone wants such a diagram of their rig, send me a PM.

For me there’s no better place in the band than to have one leg in the harmony world and the other in the percussive. Thank you Paul Tutmarc and Leo Fender.
