GiO can only be used with a Mac computer. It does not have a standalone mode.
Currently, it’s possible to aggregate GiO with another USB audio device (using the OS X utility Audio MIDI Setup), but the system may be less tolerant to sleep/wake cycles of the computer, session sample rate changes, and hot-plugging. It’s best to minimize these activities when aggregating. Keep in mind that with Logic and GarageBand it’s possible to assign the input to one device and the output to another without the need to aggregate the devices. In Logic, for example, choose Logic Pro X > Preferences > Audio, and set Output Device to ONE (for example) and Input Device to GiO.
It’s an accepted “best practice” of most audio software providers that audio files should be recorded on a hard drive other than the Mac’s Startup drive (i.e. the drive on which the operating system is installed). You can probably get away with recording a few tracks to your computer’s Startup disk, but for the best performance of your GiO recording system, record onto a separate ATA/IDE, SATA, or FireWire drive whose spindle speed is at least 7200 RPM.
GiO offers a choice of two sample rates, 44.1kHz or 48kHz. So, what’s the best sample rate to record your project at? It’s a good idea to avoid unnecessary sample rate conversion stages, so the answer is determined by the sample rate of media on which you plan to distribute your recording. If the final distribution media is CD, record at 44.1kHz. If the media is video or TV, most often 48 kHz is the best choice. If you’re part of a larger production chain, and aren’t sure, ask whomever is responsible for assembling the final product – they’ll undoubtedly appreciate the forethought.
|Once your instrument is connected, your audio software is configured and you’ve created a new recording track, just how do you set the input gain for a proper recording level in your audio software? There’s no simple answer, but with a few guidelines and a bit of experience, you can master setting a proper level. Ideally, the input gain should be set so that when the input signal is at its loudest, the level in audio software is just below maximum without lighting the Over indicator.In reality, it’s unlikely that you’ll be able to guess just the right gain setting to accomplish this – when your gain is too low, the signal never gets close to maximum and when your gain is too high, a digital Over may occur. Now, with a 24-bit system (such as GiO), the noise floor is so low that there’s no real penalty for undershooting the gain setting and recording at a lower level. There IS a penalty for overshooting the gain setting – a digital Over that results in significantly increased distortion. Thus, it’s better to work with a recording level that’s a bit too low than a level that’s a bit too high.Just how much to undershoot the gain setting is determined by the nature of the sound being recorded. As a general rule, instruments such as bass and organ have a more consistent level than percussive instruments, such as a tambourine, and may be recorded at a higher level.
Also, the performer’s skill and playing style can dictate more or less caution when setting levels. As you gain experience, you’ll be able to more accurately set a good recording level while avoiding digital overs.
|First, the expression pedal’s 1/4” connector must be a 3-conductor TRS (tip-ring-sleeve) type. Pedals with a 2-conductor TS (tip-sleeve) are usually meant for analog volume control, and won’t work properly. Even amongst 3-conductor expression pedals, there are two commonly used connection standards. Through the utility app GiOConfig, GiO supports both standards. Please see page 21 of the GiO User’s Guide for details.Apogee has tested the Yamaha FC-7 and the Roland EV-5. We will post more as we have an opportunity to test other pedals.|
Playback from any audio application such as iTunes, Safari, or DVD Player has greater clarity and dynamic range through GiO’s output. GiO’s complete functionality, including footswitch control and illuminated user feedback, is only available with Logic Pro, MainStage, and GarageBand.
Yes you can. Simply connect both devices and choose ONE as your audio input/output device. GiO’s footswitch functions will automatically be recognized, regardless of the audio input/output setting.
