## What is Pumphouse?

What do you do when you need the sidechain pumping effect in an iOS DAW that doesn't have sidechaining? Pumphouse to the rescue! 

Pumphouse is a simple and excellent compressor (taken straight from our RoughRider 2 codebase) coupled with a step sequencer driving an envelope generator. In this manner, you can sidechain-compress your pads or bassline against a 1-measure pattern, no other inputs required. 

With an easy-to-understand interface, Pumphouse is a quick method for getting That Sound. 

Pumphouse requires transport information to work. Please note that some iOS AUv3 hosts do not have a transport. (At this time, Auria Pro that we're aware of.) There is an Inter-App Audio version supplied, but it also requires transport info. 

We have tested and approve the AUv3 with AudioBus 3, Cubasis, GarageBand, AUM, ModStep, Zmors Modular, and Beatmaker 3.

### 2/5 — パラメーターのセーブが出来ない。

*2025-11-28*

良いアプリですが、
私のガレージバンドで使うとファイルが壊れる？現象があります。改善されるまで使わないようにしたほうがいいかもしれません。

使用環境　iPad 9th 
                  ios    18

### 5/5 — Pump

*2025-01-30*

Лучшее за свои деньги

### 5/5 — То, что нужно

*2024-10-30*

Красиво, легко и удобно пользоваться. Отлично выполняет sidechain компрессию на основе ритма, без зависимости от внешнего сигнала. Спасибо разработчикам за приложение и адекватную цену!👍

### 5/5 — Corrections ok

*2024-04-15*

Apparemment le plug a été amélioré car aucun plantage et aucune prise de ressources sur AUM. Parfait 👍

### 5/5 — 良いです

*2023-11-01*

複雑な設定もDAW側の対応問わずサイドチェイン的な効果から多彩な用途に利用できます。

何やら使い方がわからず悪い評価を付けている人がいるようですが説明文に書かれていますけどこのアプリは｢AUv3オーディオエフェクト｣としてAUv3対応のホストアプリが必要になりスタンドアローンとして使うことはできません。
キーボードのスクショはBM3での使用例だと思われます

### 5/5 — 楽器ではなくエフェクトです

*2023-05-05*

英語の説明文にも画像内のテキストにも書いてあるとおりこれはエフェクトプラグインです。四つ打ちなどのビートに合わせたダッキングを簡単に作れるとても便利なプラグインです

### 1/5 — 鍵盤が出てこない

*2023-04-28*

鍵盤楽器アプリだと思って購入したものの、鍵盤は出てこないし、GarageBand のAVu3にもIAAにもアイコンが出てこないです。看板に偽りありでした。何故有料アプリランキングに入っているのか分かりません。使えませんね。返金を要求します。

### 2/5 — Needs longer options

*2022-10-03*

It does what it says it does but I have to half my bpm most of the time just so I can get the whole drum pattern in which can cause issues. If it let you make patterns for more than 1 bar it would be perfect.

### 2/5 — Resets without saving

*2022-06-17*

If you save a track in GarageBand that has Pumphouse in use, the settings revert each time you open the file.

### 1/5 — Doesn’t work

*2022-04-17, version 1.1*

This app crash every time I want to use it. It’s useless

## Frequently asked questions about Pumphouse

### What does Pumphouse do?

Pumphouse provides the sidechain pumping effect for iOS Digital Audio Workstations (DAWs) that do not have built-in sidechaining capabilities. It achieves this by combining a compressor with a step sequencer that controls an envelope generator.

### How does Pumphouse create the sidechain effect?

The app uses a compressor derived from the RoughRider 2 codebase, coupled with a step sequencer. This sequencer drives an envelope generator, enabling you to sidechain-compress elements like pads or basslines against a one-measure pattern without needing additional audio inputs.

### Is Pumphouse free to use?

Based on the provided information, Pumphouse is a paid application. It does not have in-app purchases or advertisements, indicating a one-time purchase model.

### What iOS versions or hosts are compatible with Pumphouse?

Pumphouse requires transport information to function and is compatible with AUv3 hosts like AudioBus 3, Cubasis, GarageBand, AUM, ModStep, Zmors Modular, and Beatmaker 3. An Inter-App Audio version is also supplied, which also requires transport information. Note that some DAWs may not provide transport information.

### What is the main use case for Pumphouse?

The primary use case for Pumphouse is to easily achieve the popular 'sidechain pumping' audio effect, often used in electronic music genres. It's particularly useful for producers working on iOS who want this effect but their chosen DAW doesn't offer native sidechaining functionality.

## Version history (last 5 releases)

### 1.1 — 2021-01-23

> New control, "Num Steps", which sets the number of steps per measure. 

> New preset manager with user folders and auto-naming.

> Many small bug fixes and optimizations.

### 1.0.7 — 2018-09-22

Update to deal with a channel issue introduced with iOS 12 (mainly in Cubasis, but possibly other hosts as well.) Other minor bug fixes.

### 1.0.6 — 2018-07-24

Offline rendering in all hosts fixed, and tested working. Many small bug fixes and stability improvements.

### 1.0.5 — 2018-03-28

This build has various bug fixes and updates, and should be more solid than the previous version.

### 1.0.3 — 2017-12-22

Fixed a bug with Beatmaker 3 (and presumably many other hosts) that would result in crashing the DAW or Pumphouse failing to load on instance, or with multiple instances. Rebuilt with new AUv3 SDK. (Unfortunately, we had to raise the minimum to iOS 10.0 to accommodate for this.)
