I don't have one but am very impressed with what I've seen on
+++ the Alesis Website +++. This would be a great device for anyone fortunate enough to have a dedicated DAW focused recording space and lots of microphones or equipment to connect to a computer.
The product description says in part "Reverb, Delay or Phaser can be dialed up simply by adjusting the pre- or post-fader knobs located within each channel strip." I am most impressed with the statement, "you can send 10 channels (8 input channels plus the 2-Track input) individually to the computer, at up to 24-bit, 96 kHz resolution." If you enjoy recording, that is GREAT! I noticed it is reasonably priced from $50 to $100 however it is a discontinued product so it will be harder and harder to find one until they're all gone.
I noticed the replacement unit is USB compliant so it does not require computer drivers, however, it also looses the eight channel USB outputs.
Firmware updates, computer drivers and manuals are available by clicking the downloads button and then selecting what you want to download.
The user manual shows that the MultiMix 8 USB 2.0 internal effects processor has its own sub-mixer. The internal effects sub-mixer controls are the channel "SEND FX" (#26) knobs and "RETURN FX" (# 29) knob. Each "SEND FX" knob (# 26) sends that channel's signal to the internal effects processor. Adjusting the "SEND FX" knobs balances the overall blend and volume level of the signals to the internal effects processor. The "RETURN FX" knob (# 29) adjusts the internal effects processor output volume level. Press the "MAIN TO MONITOR" button and the internal effects mixer output will be heard through the headphones jack.
Notice from this description the effects signal is sent to the headphone jack, not to the main output or USB (computer) outputs. The purpose of the effects are to enhance what you hear while you're recording, the effects are not intended to be recorded.
