Bug report OS 0.27~pre16
Bug: When using the "/" key in the allowed keys of a keyboard_response item, you get the following error message:
Error: OpenExp error
Description: The key '/' is not recognized by the psycho keyboard backend. Please refer to http://pyglet.org/doc/api/pyglet.window.key-module.html for a list of valid keys.
I haven't tested if this occurs for other special keys (other than alphanumerical) as well, but maybe the mapping of the keys that can be entered in 'allowed responses' to the psychopy key has some discrepancies.
Bug: The synth_item does not generate a sound when using the expyriment back-end. It works fine with the legacy backend. Settings in synth item are: 100 Hz with a length of 250ms and a duration of 0 ms.
