	When a plugin is idle, it does not respond to MIDI or actions aimed at it. Generally, you want to turn idling off for a sampler so that you can use it even if there isn't any active audio input. To turn off idling, open the plugin window and long-press on the On/Off/Idle label. Turn off Enable Idling in the options panel that appears. '''NOTE''': when you turn off idling for a plugin, it will be turned off globally in all projects for that particular plugin.

			=== Insert vs. Bus Effects ===
			Samplers are sometimes used as insert effects when there is a single sound source. When using a sampler as an insert effect, make sure that you have monitoring on for that input in Loopy Pro's mixer. Tap the icon at the top of the mixer channel to access the monitor settings. If you want audio to pass through the sampler, make sure to turn monitoring on inside the sampler itself if the plugin has one.

			It is often preferable to use a sampler as a bus effect. This allows you to send audio to it from more than one channel, and it can be useful if you need to have monitoring off on the input channel to avoid feedback. Generally, you will want to use a pre-fader send. Long-press a send knob to access the send options.

This article provides some pointers for using samplers like Koala (or Loopy Pro itself) in Loopy Pro.

== Common Issues and Solutions ==
* Not responding to MIDI (plugin idling). If a sampler is loaded in an Effect slot and there is no active incoming audio, the sampler may be idle (asleep). By default, Loopy Pro idles effects that are not receiving audio in order to save CPU. You can turn off automatic idling by opening the effect’s window and long-pressing where it says On or Off or Idle and turning off Enable Idle Mode. NOTE: this setting is global across all projects and will apply to this plugin in all projects.
* KOALA not responding to MIDI. First check to make sure that Koala is not idle. If it is idle, turn off the idling option (directions in the bullet point above). If Koala is not idle, open its window and close it. Koala sometimes does not respond to MIDI unless the window has been opened at least one time in the session.
* Plugin blocks monitoring. If you have the sampler as an insert effect on a channel strip that has monitoring on but you hear no sound, make sure that monitoring is turned on in the sampler. Some samplers (such as Koala and Loopy Pro) have settings that determine whether the sampler passes incoming audio out of the plugin.
* Plugin makes no sound when used as insert effect. If you are using a sampler as an input effect and triggering the sampler makes no sound, make sure that monitoring is turned on for the input channel. For example, if you have Koala Sampler loaded as an insert effect on the mic channel and the mic has monitoring turned off to avoid feedback, Koala’s output will not be audible when it is triggered because that channel’s monitoring is turned off. The solution is to use Koala on a bus. Set up a bus with Koala. Add a send from your input channel to the bus that has Koala.

== Effects vs. Instrument ==
Samplers are sometimes used to play back pre-recorded sounds and sometimes they are used both record and play back audio. iOS has two basic types of audio plugins: effects and instruments. Instruments can play audio but cannot record; they have no access to audio input. Effects can both record audio and play back audio. Instruments and effects get loaded into different types of slots. This architecture is true of all hosts not just Loopy Pro.
