Я создаю тестовое приложение для фортепиано, теперь звучит вся клавиатура, и теперь я играю ноты, которые я записал с помощью гаражной группы, но у меня есть некоторые проблемы:
- ноты имеют длину 5 секунд (минимальное времягаражная полоса), поэтому нота не может быть повторена, я должен подождать, пока звучит реальная нота около 1 секунды, а затем тишина в течение 4 секунд, также иногда ноты не могут быть воспроизведены должным образом, я использую AVFoundation.framework ,,
пробовал с AudioToolbox.framework, но это дает проблемы с моим 4.1 ipod touch (не работает !!), но в симуляторе выглядит нормально
Я такжепроверил OpenAL и ObjectAL, но, кажется, слишком много для простого воспроизведения нот ??

Так есть ли способ, чтобы яможно использовать AVFoundation для быстрого воспроизведения нескольких нот?(почти совпадает с AudioToolbox) или что вы предлагаете?
спасибо!
