Software Setup

Please note: as there are so many different software packages that are compatible with the Icicle, we are compiling a list of software we’ve tested and assured compatibility.

Garage Band

  • Create a vocal track and select the icicle as the input device for that track.
  • You may need to adjust the Iciclesf’s input level in the control panel if you experience any distortion (crackling).

Logic 7 and Logic Pro 8

  • Open the Audio and MIDI setup program in your Apps->Utilities folder.
  • Create an Aggregate Audio Source (Audio menu – open Aggregate device editor).
  • Add the devices you want to use to the aggregate device (Built in audio and Blue mic).
  • Change the audio device in Logic’s audio preferences from Default to Aggregate. (To use an aggregate device with Logic)

  • Choose Logic Pro > Preferences > Audio or Logic Express > Preferences > Audio and select the Devices tab.
  • Select the Device drop down menu and choose the aggregate device from the list.

  • Select Left or Right for mono audio tracks.
  • Press “R” to arm the track for recording.
  • Roll disk.

Adobe Premier Elements 4 (Windows Vista/XP)

  • If you should experience any problems getting the program to recognize the mic, Adobe recommends the following: If the device does not allow you to record, then your microphone is not being detected as a valid input device in Premiere Elements. You can use an open source program called ASIO4ALL, which is a device driver that essentially wraps existing WDM devices, like USB microphones, as ASIO-compatible sound devices. Use the following steps to utilize this tool:
  • Quit Premiere Elements.
  • Visit the following web page and download the latest available version of ASIO4ALL:
  • Install the software, and restart the system if asked to do so by the installer.
  • Make certain that your microphone is plugged in.
  • Launch Premiere Elements. Go to the ‘Edit->Preferences..>Audio Hardware’ menu option. For the Default Device, choose the ASIO4ALL option. Click the ASIO Settings button, then select your microphone from the list of devices, click Exit, and then click OK on the Preferences dialog. Close and then restart Premiere Elements.
