    Hi,

    Just started with Podium.

    I can’t figure out how to get more than 2 VSTi’s working at once.

    I have the Audio 1+2 standard setup with a bunch of MIDI tracks using input from a M-Audio Axiom25 keyboard.

    In the list of Input sources I click on the main Axiom 1 source. But if I want to add another VST to a another MIDI track I have to use one of the sub inputs like #01.

    If I add a 3rd MIDI track with VST instrument on the new track using #01 or the Axiom’s main 1 it automatically cancels out the first. Doesn’t work at all using any other sub input from the Axiom.

    I have no problem with this in Cubase.

    So how do you get more than 2 VSTi’s working simultaneously?

    Also have big CPU use and stuttering annoyances whenever more than 1 VST is playing. Always in the red.
    Using an AMD 64 1.8 with 1 G ram, a Lexicon LambdA.

    Thanks

    Hi,

    So how do you get more than 2 VSTi’s working simultaneously?

    From your description it sounds like you are trying to set up two or more synths to be played simultaneously by the same MIDI input (i.e. layered or stacked synths). Is this correct?

    Also have big CPU use and stuttering annoyances whenever more than 1 VST is playing. Always in the red.

    Make sure you are using ASIO drivers. Try increasing the latency/buffer size to reduce the CPU spikes.

    When setting up multiple VST instruments to be triggered simultaneously using a single MIDI INPUT interface/keyboard (AXIOM/CME) I assign/drag a specific different ‘sub’ input (01, 02, 03, …etc) to each VSTi. Then by double clicking on that ’01’ or whatever ‘sub’ MIDI INPUT number is assigned (in the device list) , call up a comprehensive MIDI input Properties panel where in the ‘MIDI input configuration’ section, I enable ‘Filter input on single channel’ and then set each ‘sub’ (01, 02,..) channels to share the same channel number, usually ’01’. Each ‘sub’ MIDI input can be assigned to any of 16 channels.

    There are probably different ways to approach this since Podium is a contortionist as far as flexibility is concerned.javascript:emoticon(‘8)’)
    Cool

    Peace

    Thanks I tried rinxai suggestions and it works for the MIDI.
    I’m using lexicon ASIO driver for the LambdA and it only offers a simple config screen with More or Les CPU.

    Thanks guys

    What is the buffer size as reported in the Podium audio interfaces dialog? If the Lexicon ASIO driver is too restricted, you may be able to get better performance by using the http://www.asio4all.com driver. At least it will allow you to set the buffer size.

    The Lexicon ASIO’s dialog only has a single bar control in it – offering the CPU more less thing. Nothing else – no buffers mentioned anywhere I could find so far.

    I’ll try the 4all drivers – see what happens

    thanks

    The I/O latency is displayed at the bottom left of the Podium audio interfaces dialog.

    Ok, mine is reading 3250.

    The sound stuttering is ridiculous as soon as I have more than 1 instrument playing at once.

    That is very high. That’s close to 74 milliseconds at 44100 kHz. If you have more than one ASIO driver available in the “ASIO interface” combobox, try selecting the others. If not, then give asio4all a try.
