Meteor Multi Track Recorder DAW on the iPad: Frequently Asked Questions


Meteor not Running
If Meteor is behaving erratically or exiting unexpectedly you might be suffering from lack of physical memory. The iPad has only 256Mb of memory of which only 100Mb is available to share with other running applications (once the OS steals its share). The Safari and Mail applications can soon consume the remainder if running so in situations like this it is a good idea to exit these and other none essential apps.

To do this double tap the HOME button to display the task manager. This contains a list of running programs. Tap and hold an icon for 3-5 seconds until all the icons in the task manager start to wiggle. A small close icon also appears in the top left of each program icon. Tap the close icon to unload each program in turn then finally press the home button to return to the home screen.

If problems persist then try powering off your device by holding the ‘power’ button for 5 seconds then, slide to power off. Wait 10 seconds then power back on again. This reboot procedure will ensure that all memory is returned to the system and Meteor is the only program running.

Audio Stuttering
Meteor is a very demanding product which will attempt to squeeze every bit of processing power it can and then some! If you suffer from audio glitches or dropouts it is almost certainly due to other applications such as Safari or the Mail application hard at work trying to disrupt you. In these cases we suggest you double tap the ‘home’ button to bring up the task manager and shut down as many programs as you can (as described above).
 
If you are still suffering audio glitches after you have unloaded all other running programs and performed a power off and on again your problem may be due to pushing the program too hard with audio effects. Please read the section on Getting Started to get an idea of what is possible and what is not. In particular learn how to make use of the ‘Freeze Insert FX‘ options.

You may also want to try increasing the latency setting found in the ‘Options’ menu.By increasing the latency you are increasing the size of the internal mixer buffer which allows Meteor to be more tolerant of system interruptions. This can introduce a slight lag when listening to live input using the Record Monitor, but should have no effect on actual recordings. Using the ‘Low’ latency settings might be great for real time recording, but it can cause issues if you have many clips starting at the same time during playback. In extreme cases it can cause a clicking or momentary pause. If possible, avoid this setting on large projects or when using many effects.

I Can't Hear Any Effects
After assigning effects to your effect rack they are automatically powered on (i.e. the red power button is lit) but you may have turnThe Mixer isn't working correclty with MIDI tracks!

It is important to ensure you set the correct MIDI Out channel for each track rather than leaving them as ‘Any’ which is the default. If a MIDI tracks Out channel is set to ‘Any’ then track 1 will send volume and pan CC's to channel 1, track 2 will send CC's to channel 2 and so on. If a specific MIDI channel is set, volume and pan will be sent to the designated channeled them off at some time.

Insert effects are automatically enabled in the mixer, but Aux Send effects are not because they are global and can be applied to any track. For this reason you need to manually enable these effects on a specific channel using the blue enable buttons labelled 1-3 in the mixer. Modifying a send effect knob FX1-3 in the mixer will automatically enable the effect if it not already enabled.

Record effects can only be heard once a track has been recorded and is being played back, unless you have ‘Record Monitor’ enabled. When enabled you can preview the effects prior to recording.

FTP Transfer Problems
In order to use Meteors FTP server your iPad must be connected to a router via Wifi and not simply connected to the internet via a mobile service provider. In other words you router needs to allocate you an IP address on your local area network.

FTP transfer is more reliable if you set your FTP packages ‘Maximum Simultaneous Transfers’ to 1. This option can be found in FileZilla Settings dialog under ‘Transfers’.

See Transfer your Project to your PC/Mac in the manual for more detailed information on using FTP.

Feedback Problems
If you are suffering feedback issues at moderate to high volumes then chances are you have ‘Record Monitor’ enabled. This option should only be enabled if you are wearing headphones, as it passes audio input from the microphone directly to the  speaker for monitoring purposes. To turn off this feature select ‘Record Monitor’ from the ‘Options’ menu then select ‘Off’.

The distortion effect can also cause unwanted feedback if used with the record monitor. At times, especially when recording with the distortion effect as a ‘Record Effect’ the only solution is to lower the master volume and wear headphones. The distortion effect itself is artificially amplifying the input to the point of clipping to produce the distortion effect. The iRig adapter is known to cause a certain amount of internal feedback. Other solutions such as the AmpKit adaptor are less prone to this kind of problem. The only way to totally eliminate the issue is using a supported USB sound card.

Muting Tracks Doesn't Reduce CPU Load
You may find if you have assigned too many effects to your project things will begin to slow down to the point it actually causes audio glitches during playback. At this point you might try and mute tracks in the hope that this helps reduce the CPU load, but unfortunately this will not help matters! Meteor still processes data and effects for muted tracks so that you can drop in and out of the mix without sync issues. Consider a delay which is linked to the tempo of the metronome. It needs to keep in sync in order to resume correctly when the track is unmuted. One way around this is to mute the actual effects by pressing the POWER button on the effects in question from the Effects rack view. Alternatively you can temporarily turn off all effects processing by selecting ‘Effect Processing -> Off’ option from the ‘Options’ menu.


I Keep Losing My Mix Settings!
This problem is most likely due to the fact you have entered audomation data into a controller lane which is changing volume, pan or effect send levels on the fly. Try turning off controllers using the ‘Controllers’ option on the ‘Options’ menu and see if that helps. See the Manual section on the Controller Lane for more information.

The Mixer isn't working correclty with MIDI tracks!
It is important to ensure you set the correct MIDI Out channel for each track rather than leaving them as ‘Any’ which is the default. If a MIDI tracks Out channel is set to ‘Any’ then track 1 will send volume and pan CC's to channel 1, track 2 will send CC's to channel 2 and so on. If a specific MIDI channel is set, volume and pan will be sent to the designated channel.

I am getting no MIDI input from my keyboard!
You need to ensure that MIDI is enabled in the ‘MIDI Setup’ dialog in the ‘Options’ menu. You also need to change a ‘Track Type’ to MIDI in the tracks controller lane. The controller lane can be viewed by double tapping on a tracks ARM button.

I am having problems MIDI with Stuck Notes!
During testing we tried using many different MIDI interfaces and MIDI keyboards so we know the program functions correctly in all situations. However, we did find that some interfaces are better than others, and in certain situations we have seen dropped notes, however this is a hardware and not a software issue. You will most likely find that other iOS software suffers the same problem. Of all the interfaces we tested, the most reliable seem to be those that use the camera connection kit. If you need a reliable interface to use with the connection kit we recommend the E-MU midiTab1x1 interface which is a reliable and cheap interface whish has been extensively tested.

The Alesis IO Dock is known to have problems with both MIDI (stuck notes) and recording audio (clicking audio). This is a general problem which effects all application and is currently being investigated by Alesis. The dock works fine some of the time, just not consistantly. 

I cannot get my MIDI interface to work
Your MIDI interface needs to be compatible with the iPad and coreMIDI. If you are connecting via the camera kit adapter then your interface needs to be low powered or  self powered and require no drivers in order to work correctly. The E-MU midiTab  1x1 interface is an example of a MIDI interface that works perfectly with this software.

The Quantize doesn't seem to work
There is no realtime quantise of MIDI notes in Meteor, but you can quantise MIDI notes afterwards. The confusion probably stems from the fact there is a quantise option on the main toolbar, but this is simply for quantising / snapping whilst dragging or placing the play cursor. You need to remember the MIDI editor is a plugin so all MIDI related features are confined to the editor tab. To quantise a MIDI part you first need to select it by clicking on the part in the ruler area, or alternatively selecting a group of notes using the selection tool, then choose the 'Quantise Selected Notes' from the 'Edit' menu.

Quantize is causing sound distortion
Make sure you haven't got Swing or Shuffle on in the Tempo dialog.
