iGOG User's Guide

Downloading additional free kits:

iGOG comes pre-loaded with one kit, 'Rock Kit 1'. Five additional kits are available free from iGOG's built-in store. To download them, just press the Menu key (the 'i' located on the top right), then press 'Samples', and 'iGOG Kit Store'. Then select the Free category.

Playing iGOG pads:

iGOG features touch-sensitive pads using patent pending VelAUcity technology. For best results, use headphones, in a quite environment when playing iGOG. External noises will affect the VelAUcity tracking, and may cause incorrect hit volumes.

NOTE: If you're using an iPod touch or a 1st generation iPhone (2G), VelAUcity tracking and mic triggering modes only work when using the supplied Apple headset (or any other headset with a built-in microphone).

To load a different kit, press on the Kit Box, located on the top left.

Mic Trigger Mode:

In this mode, you can play drums simply by striking other objects (a table, your knee, etc). To enter this mode, click the menu button (the 'i' located on the top right), then choose 'Settings', and turn on Mic Trigger mode. Next, click the back arrow to return to the pads screen. Now, choose which pad you'd like to play. When you tap on an object, you'll hear iGOG play that drum. NOTE: headphones are required to use this mode. Also, mic trigger mode works best in noise-free environments. If you find that iGOG is triggering too often in this mode, turn down the sensitivity slider (located in the settings page).

Dual-zone mic triggering:

By pressing the "single/dual" button on the left of the mic triggering page, you can enable iGOG's dual-zone mic triggering. In this mode, iGOG will trigger two different drums using the mic. To use this mode, just tap an object, such as a table at different volumes to trigger the two drums. For example, a soft hit will trigger a bass drum, and a loud hit will trigger a snare. Use the balance control to adjust the balance between the two drums. To select different drums, use the pad select boxes located on the top right.

NOTE: If you're using an iPod touch or a 1st generation iPhone (2G), VelAUcity tracking and mic triggering modes only work when using the supplied Apple headset (or any other headset with a built-in microphone).

Samples Page:

This page allows you to customize iGOGs pads. To enter the samples page, click on the menu button, then choose 'Samples'. To change the pad layout, click to pad layout buttons. To assign a different sample to a pad, simply click on one of the pad boxes, and choose select to assign a different sample.

Note: The iPhone has a limited amount of memory available. If you choose samples which contain a large amount of multisamples, you may only be able to load a few samples. iGOG will alert you when choosing samples. If you receive this warning for a particular sample, go back and choose smaller samples for some of the other pads.

iGOG can also play your own samples. Standard wav, aif and Drumagog gog files are supported. To use your own samples, first copy the samples from your computer into iGOG (follow the instructions below for the File Transfer Mode). Then, go to the samples tab, choose a pad, then press the select button to find and load your sample. iGOG supports 16, 24 and 32 bit samples.


iGOG's sequencer allows you to record midi sequences, which can be played back within iGOG, or exported to your computer. iGOG can also load standard midi files.

Using the sequencer is easy. Simply press the record button, then start playing the pads. To hear your midi sequence back, press the play button.

To erase a section of notes, press the record button. Next, hold down the erase button (located at the top left of the screen). When you hear the section you wish to erase, press the pad with offending drum (while still holding down the erase button). Let go of the pad when the section you want to erase passes.

If you'd like to hear a metronome, go to the sequence page and turn up the metronome using the metronome slider.

The count-in function counts 4 beats before recording. To use this function, select 'count-in'.

The quantize function automatically adjusts the timing of your playing to a particular beat. This is especially useful for recoding live drum parts, because your timing doesn't need to be perfect while playing - iGOG will fix it for you. To use the quantize function, simply move the quantize resolution slider to a preferred value (1/8 is a good starting point). The quantize strength slider adjusts how much iGOG should fix your timing (for a more human feel, choose 60-70%).

The tempo can be adjusted by either moving the tempo slider to the desired position, or by taping on the 'tap' button below the slider. To use the tap tempo feature, tap the button more that two times at the tempo you'd like.

The time signature is adjusted by moving the time signature slider. Signatures from 2/2 to 12/8 can be set.

NOTE: The time signature cannot be changed once a sequence has been recorded.

To save and load sequences, press the 'MIDI File' button. iGOG will read standard MIDI files, and will correctly interpret tempo and time signature maps.

Backing Track:

iGOG allows you to record drum parts in perfect sync to an mp3 file. To use this feature, press the 'Backing Track' button (located in the sequence page), and choose an mp3 file. Next, press the record button (on the main pad screen), and play the pads along with the mp3 file. When you're finished recording, press play, and note the playing is in sync with the music. This feature can be especially useful if you're a musician, and you want to practice to a song you're working on. After you're done, you can export the midi file out of iGOG by pressing on 'midi file', and choosing 'Save MIDI File'.


iGOG features a mixdown mode, which creates a .wav file of the sequence you've recorded. To use this feature, press the 'mixdown' button (located in the settings page), choose a name for the wav file, and press ok. A wav file is created and saved in the 'Mixdown' folder. You can access this folder from your computer by using the file transfer mode. See the File Transfer Section below.

File Transfer:

This feature allows you to move files back and forth from iGOG and your computer. A WiFi connection is required to use this feature. To use File Transfer, select the file transfer tab, and follow the instructions there.

Purchasing Additional Kits:

iGOG features a Kit Store which allows you to purchase additional kits. To access the store, select the Samples tab, then press 'iGOG Kit Store'. Purchases are automatically deducted from your iTunes account. After purchase, the kit is downloaded onto your device. If a download is interrupted for some reason (for example, a phone call), iGOG will automatically resume the download the next time you run it.

If you are using a new device and wish to restore all your previous iGOG purchases, simply re-purchase all the kits. You will NOT be charged again for these purchases.

Loading Drumagog GOG files:

iGOG can load and use standard Drumagog GOG files. Simply copy a GOG file into iGOG's Samples folder (using the file transfer function), then assign it to a pad (see Samples Page above). Note: positional samples are only supported on the Hi-hat and Ride rectangular pads.
