    Latency: Tascam US-122 with GigsaStudio

    I asked a vendor to recommend an audio in/out midi in/out to use in conjunction with Gigastudio 160.

    He did some research and advised he talked with Tascam and came back with a recommendation of the US-122 -- a USB Leverl 2 device. Since Tascam makes the software as well, I thought it would be wise to have responsibility for any incompatability sit with just one company. I ordered US-122 along with Gigastudio and they arrived today.

    I started reading the Gigastudio manual and found the following \"Note\":

    2.3 MIDI Interfaces
    ...
    Note: ... we have observed distinct advantages to using ISA or PCI based MIDI interfaces, as these provide the best latency performance when used with any MIDI software. Parallel port based MIDI interfaces provide slightly slower latency performance, while many USB interfaces add up to 5 ms of timing latency and should be avoided if possible.
    <font size=\"2\" face=\"Verdana, Arial\">Before I open the US-122, and or go back to the vendor, I\'d like to know of anyone\'s opinion about the above statement vis-a-vis Tascam\'s own US-122.

    I plan to feed MIDI from a controller into GigaStudio for live performance and I\'m not sure a 5ms latency, if such occurs with with a US-122 on a fairly up todate system, is acceptable. Perhaps it is possible the Note was made in reference to older versions and USB 1 rather than the USB 2 that the US-122 is designed for.

    Would anyone with a US-122 share what their latency has been?

    I called Tascam\'s technical support and spoke to a product specialist who advised that the language used in the printed manual shipping was created at a time when USB ports were unreliable. He assured me that the US-122 would not present any latency problems when using it with Gigastudio.

    I have the US-122 with Giga 160. The US-122 is GSIF compliant, so think of it as just made for Gigastudio. Latency is said to be an excellent 3ms.

    I actually bought the US-122 for use with GS160 with a 866mhz laptop, and had terrible problems with latency. If I reduced the latency as suggested in the manual, polyphony was completely screwd up, I couldnt even play more thn a few instruments at a time.

    maybe I was doing something wrong but I had to return it.

    the echo indigo does a great job though and if you need just one audio input they have the indigo io for just 160 or so.
