Stamp Album consists of a plugin host, some stamp sized plugin effects and state saving adaptors the attach to the edge of the effects as they are added to the plugin host. 
Each adaptor can save 50 different settings and there are 50 pre-made adaptors. The adaptors are numbered purely for convenience and the number only reflects the start position (if multiplied by 50) of the array that is saved or loaded, therefore any adaptor can be attached to any added effect, that pairing has to remain permanent for that host environment to preserve the preset saving/loading integrity

To start using Stamp Album

First open plugin-host.pd then Save As... eg. 'my-plugin-host.pd' (to the same folder as 'plugin-host.pd') 

Click on 'set directory' in the load/save box.
Navigate to the 'plugin-presets' folder, select any file and click open (at least one file needs to exist to select)
Now from the PureData file menu select 'Save' (this will save a message box with the 'plugin-presets' folder path)

Then add an effect from the menu on the left. eg 'Delay' now in edit mode drag an adaptor from the right to close to the right side of the new effect then, from the bottom/right of the effect connect to the top/left of the adaptor and from the bottom/left of the adaptor connect to the top/right of the effect. It is useful to do this as you go when adding effects so that any changes to the effect are written and therefore can be saved to a preset file.

Next Connect the output of 'adc~' to the audio input of 'Delay'
Then Connect the audio output to the left and right audio connections of the audio-output module (the black box with the VU meters)

Next make the adjustments to the effect

Play away

Now Save the settings using load/save box as 'my-delay'

Habitually save the host environment when adding/removing effects wiring/rewiring effects and Save the effects preset settings when happy with the result, but do remember to use a new preset name if you wish to preserve the previous settings.

It is important to only load presets back into the same host environment they were saved in. Creating a seperate folder for each hosts plugins and setting the folder path with 'set directory' would be one way to ensure this

Requirements:
Pd-Extended
A 'plugins' folder in main patch folder
A 'plugin-presets' folder
