I'm just starting to use BioEra, with Q-Wiz, and am running into several difficulties. I'm sure there are things wrong with my setup.

1) I can resize the charts (polygraphs) that are in separate frames, but I can't move anything -- everything is frozen -- on the main pages (Runtime 1 & 2), even when I set Chart / Runtime Display / Unfreeze Screen.

2) Starting and pausing/stopping the session starts and stops the audio feedback, but nothing at all happens on the charts (polygraphs) or oscilloscopes. There's just the blank grid.

3) For audio feedback, I'm using a SoundFileReader to generate input into a PCMAudioPlayer, where the volume is controlled by input from an Expression Evaluator. The sound plays (quietly), but the volume is invariant, even when I set the Expression Evaluator to 0 or 100 (or when I delete the volume input link).

4) I would like to set it up so that when someone clicks on the Button element, that point in time is marked in the polygraph charts. However, no connection from the Button element to a Polygraph element is accepted.

Please advise.

Thank you.

1) Only one chart can be put in a separate frame or dialog. So it can't be resized, it has the same size as the frame/dialog it is in. Charts can be moved/sized only on Runtime1 and Runtime2 frames.

2) It seems you must have connected something wrong. Check if the examples which come with BioEra work. Or send a snippet (a small design which demonstrates the problem) to this email: http://proatech.com/email.html

3) I created a snippet which demonstrates how to change volume using ExpressionEvaluator:

4) There is no such option available.

Thank you, Jarek. However --

[I'm keeping the same item numbers as in my original post and your reply.]

1) Regarding resizing the charts on Runtime 1 & 2, the solution was to select Chart / Set Edit Mode. I should have seen that before.

2) Regarding nothing happening on the charts, I'll send my design to you in an email. I wouldn't know what to select out as a snippet, because I don't know where the problem is. Thank you for the invitation.

3) Thank you for the snippet. When I run your snippet with the minimum value in the slider set to 0 and the maximum set to 1, I hear nothing at any position of the slider. When I set the maximum value to 100, then as I change the position of the slider (sliding between 0 and 100), the nature of the tone varies, but the volume stays the same (quite low and invariant, like my own design). Also, I do not see the F_NumericDisplay chart. I see only the design screen and the volume slider.

4) The button has two logical outputs on the side (out & negated), and two event outputs on the bottom (E1 & E2). What can these outputs plug into? When I've tried to plug the logical outputs into something, I get "Input-Output types are not compatible." When I've tried to plug the event outputs into something, I either the attempted connection vanishes or I get "Event output must be connected to input event pipe." When I search the manual for "event pipe" I get no results.

Thanks,

Jaxom

3) I run the snippet I gave you on 2 computers, both with the same behavior. So I am not sure why it works differently on yours. Do you have more than 1 sound devices? Like for example speakers and headphones (if so, then you might want to enable only one of them in Windows Audio settings)? My volume changes between values 0 and 1 on the slider. I can increase it up to 4, and then it starts to distort (which means the volume is maximum possible). It is also possible that your sound device is set at a very low volume in Windows, try to increase it there. The volume which is set in BioEra is completely independent from Windows volume settings.

4) It is not about the Button. It is about Polygraph, which doesn't have an option to show a time mark.
